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?

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.

Exactly!

I tried it twice and both times failed miserably.

I've had 100% success with just digging a tiny finger sized hole in the soil about 2 inches deep and watering every now and then.

Amen.

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.

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.

looks like phosphorus deficiency.

Maybe your plant is so big it needs even more phosphorus.
But I am noob so you probably should disregard my guess work.

is there an unwritten rule about spacing when growing cannabis? can plants be too close together? you obviously want them to have enough room to grow to their maximum potential but beyond that, do they need additional space?

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.

thanks for the response and valuable information. let me know if I have this correct: outdoor growing requires more space to grow a larger plant over a longer period of time, and growing indoors takes less space but plants grow faster due to better light sources?

>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.

LED burn or not

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.

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.

New development, I meassured temps and it turned out to be at least 35C-40C inside.
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.
Did some rearanging and shit and tried adding some cooling elements to the equasion, hoping to knock it down to atleast 29C, will check in the morning

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?

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.

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

What plants and flowers can I grow in the same pot as my weed so it would make my grow less obvious?
A plant that grows roughly at the same speed during the first weeks would be great.

Im asking because I'm starting a window board grow. I live in the fortunate situation that only fellow students can see what I do and my window gets about 10 hours of direct light per day. Enough for an automatic

When they get real tall or obvious I plan to move them inside, under artificial light or behind my windows, which I would outfit with diffusion foil.

Second time grower here. I previously grew one plant and it turned out okay. I decided to try again. Bought two clones from a dispensary and transplanted them into my grow tent 3 weeks ago. Originally, it looks very healthy; in fact my other plant was the one that was starting to wilt. A week later, the tables had turned and my previously wilting plant exploded in growth and looks really good now. However, one of my plant's stems aren't growing longer, it's only growing fan leaves. Anyone have an idea why this is happening? I couldn't find much information about it.

A little bit of info regarding my set up: 6x3x3 ft grow tent, 125W lamp, 2 inline fans with proper ventilation, 2 more small circular fans inside to circulate airflow. Both plants are using the same medium + nutrients. pH level is 6.8, fairly normal.

russet/broad mites is my best guess, your healthy one has is too. i had that little curl on the serration tip last summer when i was trying to figure out what was going on. once shit got worse i figured it out eventually, but i was on potassium deficiency from overwatering for a week and nute lockout from too much foliar calcium for another before i decide to try pest control. shit gets bad if you let it get out of hand, but it can be beat pretty easy with the right stuff. a lot of the right stuff you don't want to be applying near flowers though. you can beat them back with out completely eliminating them and then apply DE for further control and rinse the DE out of your flowers once they have resin on them. seems to me like russets don't eat the resinous part of the plant. i have russets in my garden on my veg plants right now and i have autos flowering nearby. i don't spray the autos at all and they don't show problems, if i stop spraying my regulars (still in veg) for 5 days i start to see russet damage so i have this idea that if you can nurse you plant along far enough into flower eventually it protects itself from the pests.
