I've been using neem oil for about two weeks now, once every three days before lights out. The last living mite I saw was about three days ago, I sprayed them again last night.

I actually started all five seedlings in mud in plastic solo cups, the best dirt I could find around my house. I mixed it up pretty well and added some mulch, and once they sprouted I mixed a bit of tomato food into the water before watering them. Since I've transplanted them I've given them nothing but neem oil & water

It looks like a lack of light. Its internodes are few and far apart. The leaves look pathetic like they can't photosynthesize properly. Nutes are there as it's burning but not enough light to use em.

Give it more light. Ventilation for more light. Problem solved.

think the nutrients are burning the leaves??? see the webs and holes on the leaves? I'm at 4250 Lumens currently, I assumed it would be enough. Also it has tons of ventilation and fresh air, though I've been cooling my grow room because I heard it makes it harder for the mites to reproduce.

I planted 16 seeds about a week ago from a reliable breeder.

In a few days, 3 popped. In a few more days, 2 more popped. Now it's been nothing for a few days. Am I being too impatient, my time perspective off, or should I lightly unbury and see if they popped a tap root or will that do more damage than good and just let them sit and if they make it they make it but if they aren't gonna make it nothing I do will help?

I used to unbury the seeds all the time when I was starting out, and if they poped a root you can usually see it without unburying it too much, so if you are curious I say go for it.

I do not understand why people keep advising this paper towel method.
I have a 100% success rate of germinating in streight coco and once I tried the paper towel method, since hey, I wanna be cool and proffesional like those other guys, but ended up with 1/4th of my seeds not germinating.

I mean you should always do what works best for you but the paper towel method is tried and true, it seems possible that 1/4 of seeds you used were bad to begin with. I've personally been successful with this method, but there's always the odd seed that simply doesn't want to sprout, I can't imagine starting them in cocoa would make a difference.

Yeah, I wanted to add that this is just my personal anecdote and doesn't mean shit in grand scheme, since, yeah, maybe it was the seeds, maybe I did something wrong, maybe storage issues by me or place I bought it from (although those were just regular seeds I always buy), but forgot.

Planting them already sprouted was pretty cool, but imo streight to substrate is much simpler. I just put those fuckers horizontally-ish, cover them up, add some water, couple days later, bam, a little green bastard.

On my last grow I used 20L bags, and since the substrate was already wet, since I usually rinse it thoroughly in case the manufacturer didn't give a shit about salt and other contaminants. I just added some water, with 1/2 - 1/3 the usual nutes, once when planting, and a tiny bit the next day. And that's it, and I probably could've skiped the second watering, the substrate felt wet enough.

Best plant I've had growing so far.

I have a gorilla glue autoflower here with (probably) a wide range of problems but am not sure how to proceed.

It's at 16 and a half weeks from seed, however while LSTing about 2 weeks into flower I accidentally snapped the head off. This led to it growing really wide and fat.

During most of the summer the temp was sitting at 32c, obviously too high but nothing else I could do. I also found some bugs on it during the summer, however they appear to not be there any more as far as I can see. The other plants in the tent were not affected by any of these problems and are doing just fine.

The actual problem I have is although the buds are fat, the pistils don't seem to be turning orange. Some are, but it seems to be stalling / going very slow.

Leaves were yellowing as if it were finishing, but some have dried up with some dark spots on them. Just wondering if it will actually finish or if I should just call it and cut it down. The buds are sufficiently fat, it just doesn't look fully finished.

I tried growing in nothing but perlite with some gravel at the top and I got something munching on my roots big time. I want to try a deep water culture again. If you can control root zone temperature and oxygenation and light exposure you don't have many issues. I think maybe I could convert an old mini fridge to a root chamber. Maybe put some plexiglass in front of the opening so I can open the door of the fridge and look at the roots. Put an air stone in there and pump it full of bubbles and you get super fast growth and you can easily induce drought stress on the plant during flowering to simulate the dry season that causes resin production to increase to seal off stomata and avoid the plant from losing too much water by just letting the water level drop a little bit lower than usual before adding more water.

I actually got a pretty decent harvest, because the plant built an extremely extensive root structure during vegetation. I took my time and topped it a few times so that I would get 16 symmetrical main tops which I made fill the entire space with low stress training by tying down the branches with soft rubber coated wire plant ties and duct tape. During flowering the colas got super big, longer and thicker than my forearm. I noticed whatever was munching on my roots right when I was debating changing it to flower at the end of a long veg, that settled the debate and I started to flower. It worked quite well but eventually near the end the little critters had basically eaten the entire root structure so it didn't finish quite right I think. Still it was an amazing flavor and high.

Growing in perlite is a good option if you can keep it sterile I think although deep water culture is safer imo because few critters can survive being fully immersed in water. You can add worm castings to a deep water culture to get beneficial bacteria and fungi that help protect the root zone. Change your water every couple of weeks and each time mix up an extra amount of nutrient solution and clean your air stone or whatever you're using to oxygenate the root zone. Save some of your extra nutrient solution to add in later when the plant drinks it. Add fresh worm castings only to the root chamber not the extra nutrients because the beneficial microbes won't survive in water without it being oxygenated.

My best weed came from when I did this. I had a small rockwool starter cube that I placed the germinated seed in, then I put that in a small net pot filled with perlite with gravel on top. This small amount of perlite was pretty good I think because the perlite sucked up moisture from the reservoir beneath it and wicked up moisture to the rockwool but the rockwool was above the water so it had pretty good oxygenation. You just need to make sure the bottom of the net pot is submerged in the water. Just run straight water until the second set of true leaves form then add 1/8th of the nute bottle's mixing formula and slowly titrate up to maximum strength over the course of a month. I did it in a 5 ga…

BTW I have used both CFLs and LEDs and I recommend them both. If you want to do a cheap CFL setup you can get a couple of power strips and some adapters with a slot to screw in a light bulb on one end and a plug on the other that you can plug into an outlet to power a lightbulb. Turn the power strips back to back so that the power outlets are facing outwards, then plug in three light bulbs on each side. You can zip tie or tape the power strips together. This makes a ghetto light fixture that is cheap and can work with CFLs. Use standard size 20-30 watt (actual, not equivalent) bulbs in the correct spectrum that come in the standard size. You can put a reflector of some sort of white or shiny material like mylar above the lights so that the light emitted by the cfls that goes up is redirected to the plants below. CFLs emit the most light from the sides of the bulbs, not the tops so this fixture is optimal as all 6 bulbs are placed with the tops pointing out to the sides and the sides of the light pointing up and down. Two of these will cover about one to one-and-a-half square meters. You can also choose to put pairs of 2 on each side rather than 3 or split up the strips so they're not in pairs. The less bulbs there are clustered together, the less heat there will be and the closer you can get them to the plant canopy which means the more intense the light the plants are exposed to gets. Led light fixtures are neat and probably easier to work with and have even better cooling and efficiency than florescents. You can also get really into building custom LED setups if you're into electronics but I've never messed with any of that.

Your plant can take in as much light as you can give it in a deep water culture because there's an optimal amount of water. The plant will just respirate away like crazy and build and build and grow and grow. You can be aggressive with your nutrient feeding as long as you are religious about keeping your PH optimal. This is where most people fuck up. if your ph is fluctuating each time you change your reservoir or when you add in more water in-between changes, your plant will be stressed and/or nutrients will be locked out and plant growth will suffer a…

Thats a pretty great guide to growing indoor hydro you packed into those two posts. Good to know your plants turned out nice too, on the topic of pushing maximum light, I'd love to see someone take hyrdoponic growing outdoor and really push things under sunlight, possibly using reflectors of some sort to add to the intensity of the light. Very few people run anything near solar intensity lighting inside and those that do only run it at that intensity near the tops of the buds. Outdoor hydro could be the best way to combine maximum light intensity with max nutes.

I had problems with overwatering before. And/Or roots not getting enough oxygen.

So this time around I got those fabrique pots (smart grow pots or something) for 20L (this is about 6 gallons in imerial units) put the medium there.
One is only coco, the other is coco +20% or so perlite. rinsed them and all so they were soaking wet.
The dried for 2-3 days while I was getting my seeds (both auto) I put em there, added some water with my minerals on top of them (just a little though) they sprouted and all, since they sprouted it's been about 10 days and in that time I only watered them once with about 200-300ml, that was about 2 days ago and the soil was dry for 5cm (2inch) in.
And while all this time they've been growing quite good(the best I had I might add) I am worrying of missing wattering, but at the same time I am paranoid of overwatering as I did before.
Got any good tips? Or maybe some advice on how to judge if I should water based on plant condition?
my theory right now is that the plants keep growing roots that grow into wet medium so that's why they've been Ok, and if what they tell about roots being twice as deep as the plant is tall is true then the roots definetly have access to moisture.

So yeah, anyone got any tips for paranoid overwaterer.

Any ideas what causes this? It's almost exclusively the lower leaves doing this and some lowest small flowering branches nodding off or browning and dying but they are like 3 feet from the lights anyway.
The monsters are about 5 feet tall so obviously light penetration in the lowest levels is slim.

Been some 2 weeks in flower counting from first pistils.
Hydroponic, using bloom:micro in 2:1 ratio, EC around 1.3-1.5, but it keeps rising so I'm going down to 1 slowly. Doesn't seem to be nute burn though.
Using liquid silicon occasionally at 1 ml/litre. Sometimes adding hydrogen peroxide 1 ml/litre tops. Using top max 2-4 ml/l.
PH fluctuates approximately between 5.7-6.5 depending on adding new water etc.
Temps may be a little high but not super overkill. There is colder intake blowing under the canopy at almost ground level. Not sure if too cold.

They might have windburn, or it could be the plant just putting more power into the buds and killing off the leaves that don't get as much light. The wind can gently rustle the leaves, but if any of them are waving around constantly or swaying hard it's probably windburn.

Oh yes. I made this mistake this year with my first outdoor grow, planted my seedlings only 4 feet apart. The result was one plant that grew into a 4x4 and 6 foot tall monster hogging all the sunlight from the remaining plants which suffered from the shading but still tried to grow into the big one. I was able to train the shaded plants to grow outward so that they can get more sun, but they could have done a lot better with some more spacing.

Now indoors is a different story, with a bigger space you find yourself needing a better light source so more space isn't always necessarily better there.

>outdoor growing requires more space to grow a larger plant over a longer period of time

Thats one way to look at it. You already have the most powerful light source available: the sun. So the more space you give your outdoor plants the more space they have to spread out and grow big without running into each other. I put my plants directly into the ground so there is no moving them, but if your plants are in pots obviously you can move them however they need.

>and growing indoors takes less space but plants grow faster due to better light sources?

I wouldn't say indoor lighting is better. Actually with indoor lighting limited in the amount of space you can use because your light source is smaller. The difference is that indoors you have control over your plants and when you want them to flower, so you can harvest a lot sooner than with outdoors. Whereas outdoors you are at the mercy of mother nature.

I think I might have killed my plant with too much LED.

Had a plant growing under 7 5.5W bulbs and one 50W (All actual draw) at ~40cm height (15 inch)
It was doing fine, not great but good enough.
Then I got two more 50W leds and placed them on at the same heigh.
At which poing my plant basically stoped growing completly and the leaves started slowly turning yellow. I though it was because I overwatered it twice in a row(got almost 50% run off both times) and that's what caused leaves to yellow and stunt growth.
Then I planted new seed. it sprouted grew first two real leafs then they raised almost vertically and then they slowly started getting yellow too, like on the previous plant and it didnt grew one bit for about 5 days now. I did place it at about 60cm (23inch) heigh on the 2nd day or so but it didn't help

The space is 60cm by 60cm so about 0.36 m2 (3.87 square feet), medium is coco.

So, is it LED burn after all? Or some other combination of things?
If it's LED should I take out some LED's or put them higher?

pic is not mine but looks similarly, although mine were more yellow than brown.

If you're overdoing LED light intensity the flower will bleach white, but won't otherwise look harmed. Its kinda neat you should try it sometime. Your problem is something else; heat, overwatering, underwatering, potbound, too much nutes, not enough nutes or it might just be a natural fade.

Once the roots fill the container, you're supposed to keep it wet. Treat coco as hydroponics and make sure you get runoff every watering. If you let the coco dry it'll start accumulating salts which in turn start to lock off nutrients, fuck up the pH and burn the plant.

it's usually cold as fuck where I live, so I was disregarding temps completly, but there has been a heatwave going on and it didn't help that those new 50W leds were actively cooled by fans.

Bleaching has nothing to do with intensity and everything to do with missing spectral components. It only happens with those red/blue disco lights.
Full spectrum white LEDs don't have these problems, and they have become more efficient than the narrow spectrum ones in the past years.

I have a tent that is 41 cubic feet. I have 29k lumens from my LED lights. Will this be optimal for that tent space? I don't care about heat, just whether that lumens per cubic foot is good with LEDs. Does anybody have an idea or does it entirely depend on the LED spectrum?

anything more than 1000w/square meter is overkill

>Cubic feet
Totally useless measurement
What the square footage?

Oh you americans

Actually it's even half of that. 400W/sqm is considered optimal.
You can go higher, and get something out of it but you'd have to utilize some vertical growing techniques like V-sog, scrog/lst.

LED spectrum wise, get warm white 2700-3500k low cri high efficient LEDs should be at 160-200 lumen/watt (yes 200, check out samsung linear led modules)
These are better than any possible red/blue light at this point. Don't buy the purple crap, nobody in the greenhouse industry uses them.

The sun puts down about 1100watts per square meter. Does it for free too. If you could control the heat and pay the power bill at that density of light indoors the plants could almost certainly handle it. Maybe if you lived in Barrow, Alaska, kept your tent outdoors during midwinter and powered it with stolen crude oil.

Most of the suns energy isn't used by the plants. And that 1kw /sqm figure is true for high noon near the equator with a clear sky, so...
Anyway that 400W / sqm figure is a general ballpark figure for indoor and it has some caveats.
That was true for HPS light (if you use highly efficient leds it's actually a little bit lower even) and it is meant to get the most out of a particular light meaning:
If you give it more space the quality of the product will suffer, if you give it less space the yield won't be as high.
Of course if you want to get the most out of a particular space you go with more light intensity.
1000W / sqm is still too much (not to say it won't work you are just wasting power and making it hard on yourself.)
600W / sqm if you want to get the most out of an area. Any more again you will be wasting power and it will be harder to keep cool.

So i have 3 plants over here and theyre all in 40l pots, two of them are getting these discolorations, besides that they look very healthy. Should i be worried?

I think you should worry, google "leaf miner"

If its just one spot you can just remove that leaf and nip it in the bud that way a lot of the time.
