These 2 Auto Ak47s have been yellowing since about week 5~ I didn't give them any nutes til week 7 (fuck up #1) but I flushed them with 1/4 GH Flora Trio. This was one week ago. I had to go out of town and returned to find my plants pretty sick. Pics below 4 days ago: http://imgur.com/a/BjC0g today: http://imgur.com/a/NwUUS

What should I do? They've been on a 24hr schedule since sprout. I haven't watered them since I left (7 days ago) I just got home the soil is bone dry. Do I flush with nutes again or plain water? I also got some calmag shipped while I was gone (I thought this might be the deficiency I was looking at), Should I add that only with some water? You can see my grow diary here: https://growdiaries.com/diaries/838-t5-auto-ak-47-msnl/week/3514

Always PHed water/nutes to 6.5 and I phed the runoff 7 days and it was at 6.0. I think I'm looking at 2 different deficiencies now, any tips at all? How fucked am I? Obviously the leaves won't recover so I'm not sure what to do.

Medium: FFOF
Lights: 8 2ft T5s

Looks like a Cal/Mag deficiency. If she's at week 7 of flower her foliage still looks pretty good over all. I would worry when her sugar leaves start to turn. What week did you plan to harvest?

I ended up giving a good watering with some 1/2 dose GH calmag and raised my lights a little bit to give them a rest.

>>144189
It is day 52 from sprout so harvest can't be to far off right? 9-10 weeks seems average. I was hoping for 10 weeks but 9 (12 days from now) could be all I get.

I think they'll make it 2 weeks if they need watering again soon so I can get 1 last feed in before a flush or is this a bad idea? This would be pushing them as is to week 10-11~

If it were me I would probably just feed it plain ph'd water and rely on the plant using up all its nutrient stores in the leaves and rootzone for the last two weeks. You could do one last feeding and then flush the last week though. This late in flower they look pretty good though, I don't believe you should have super green leaves as it just means you have more N to flush out before harvest

I have a blue cheese plant here that is almost at week 15 of flower. I've read this is normal for the sativa pheno, but while almost all of the trichs are cloudy, no amber yet, new white pistils are appearing.

Does this mean the bud is still growing / putting on bulk and should be left longer, or should I just chop?

it will keep on flowering as long as you keep on giving it 12/12, water & nutes. i've seen people flower plants for over 60 weeks. most people harvest when the first flowers are fully mature. plants with nice looking fades indoor which look like naturally finished outdoor plants only look like that because the grower stopped giving nutes & probably turned down the room temp too.

harvest according to the color of the trichome for the desired high. While the darkening of pistils can be used to tell when harvest time is, they are not as certain for reasons such as these. Amber = Stronger, couch-lock properties of strain shows up, Cloudy=Energetic, sativa properties of strain shine through

Ignore the new growth. It is just something they do sometimes. Just make sure you judge the trichs on the OLD parts of the bud.

I have a sativa and a hybrid that seems mostly "sativa like," and they are both in their 14th week. I figure the sativa has literally another 3-4 weeks at this rate to go. The hybrid will probably be done by friday.

For 4-5 medium sized plants you should go 250-400w.
Less is more in my opinion.
Choose whats best for you.
More wattage > faster growth > less veg time > faster buds
But there's a flip side to this.
More heat from the hps > more fans needed > more electricity used
Faster growth > more "caring" needed > gotta keep studying on the techniques
Less veg time > less time to get to know the do's and dont's > more room for error
Faster buds > Don't always equal dankness

But yea, there's a lot of things to be considered.
The equipment is only half the battle. Gotta go with the proper strain as well.
I would start with something that's described as hardy, sturdy and beginner friendly.
Preferably an indica, because their upkeep is usually easier.
Also if you're impatient like me, get something that has 6-8 week flowering time.

Yo first time growing, outdoors. 4 plants, Lemon skunk, just began flowering this week... However, at beginning of the week I had a few cool/drizzly/humid/calm as fuck days and one of my (extremely bushy, unpruned) plants got infected at a couple of nodes on the main stem near the middle, and a couple of branches with grey mould. It only seems to have taken hold in/near the middle as I think they had far too many leaves crowding around, trapping the moisture in/restricting airflow etc.

I have pruned her around the parts she's infected, sprayed her with a diluted liquid copper fungicide, removed the leaves directly surrounding the areas to get more air circulation in and around her bush, and taken her about 10 metres from the main grow area. Thankfully, I think caught it before any branches/the stem had been eaten through/broken entirely. They don't seem to be showing any signs of major damage except at the ground zeroes of infections. None of my other plants seem to be infected (yet) so I'm hoping it was just a ventilation issue as she was the most tightly packed bush of the litter, and there has been no wind lately (There were massive gales they were used to before). I have also sprayed the others with the copper fungicide just in case.

Given that none of her (very young) buds seem to have been directly infected, and I have pruned her, exposing the infected areas to more light/air circulation, will this continue to adversely affect my plant? I've read in some places that the plant should be discarded entirely if it is infected, but this advice only seems to be given when the buds themselves are infected (It's only stems/mid main stem nodes so far) Should I put her down?

tl;dr outdoors, week 1 flowering, grey mould on stems - not buds, pruned around for more air, sprayed with copper fungicide, wondering if she should be put down or if it's possible that she can stay strong until harvest

Pic related, one of the infected areas before I sprayed/pruned, the stems are still intact/structurally sound for now.

Any advice would be greatly appreciated

Thanks in advance

I have a 120x120x200 tent with a 600w (230w actual draw I think) LED and want to grow 2 plants, one indica and one sativa.

I plan on topping / LST to try and keep the height the same on both plants, however am looking for advice / tips on keeping such different strains the same height to avoid having one stumpy plant not getting enough light.

Should I plant the indica a week or so before the sativa to allow it to get a headstart?

I'll most likely do this if worst comes to worst.

My last grow was 2 blue cheese plants, one turned out to be the super compact, really cheesy pheno, while the other was a super lanky sativa dominant pheno that took 14 and a half weeks to finish.

Really fucked me because I didn't have a very powerful light at the time and the short plant suffered a fair bit from not getting enough light. The longer finishing plant was something special though.

This is the best idea.

As is planting the sativa a bit later. Sativas take longer to finish anyway. At least in my experience. So, planting it a couple or three weeks later might be the optimal answer.

Even if I start the sativa earlier, they'll still both be in the same tent so flowering will have to start at the same time. I just wanted to plant the indica earlier to give it a chance to get some veg in before the sativa starts outpacing it and getting too tall.

I was thinking that staggering the planting would help give the indica a chance to soak up as much as possible in the early flower stage when the height is put on. Ideally, it would be tapering off as the sativa went in, so you'd get a longer period where the indica "dominated" the available light.

But, that's just me speculating.
It can also be tricky to guess anything, because unless you are using clones, the phenotype you get from even the same plant can vary a fair bit. Maybe the sativa ends up being more inidca and shorter, or the indica gets leggy. Throw in all the issues that can come up with improper feeding, etc. You never really know.

I am interested in starting a small home grow setup. I have 2 plants that are growing pretty well, but one of them has all but outgrown the shelf I was growing it on. It seems to me that the best course of action at this point would be to get a growbox. I believe I would be using LEDs for my grow because they are fairly inexpensive and efficient. I am looking for something relatively small and discrete, and preferably inexpensive. In particular I was looking at this tent listed on Amazon.
amazon.com/gp/product/B01AWBDL4I/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A3AN9QJNQ0FYAY

I am a total newbie to this, and I need some guidance. Is it a good idea to get this tent? Would it be able to accommodate my 2 plants? Would a LED grow dramatically affect my electric bill? What are ways I can reduce the odor of my grow operation? Would it be feasible to contain this small grow op within my 1br apartment, or would it be too risky? What should I do with my plants if this is not feasible?

Your biggest issue will be odor. You can pull this off, but it will be tight.

For the lights go with a 400w or 600w switchable ballast for HPS/MH. LEDs are OK, but honestly seem to do better for keeping mothers and clones going.

The filter protects from shit that is too small getting into the system and fucking it up. Logic dictates you should keep the filter in.

What you should do is figure out the size of THAT filter and get a big screen that is that size or smaller. Then, filter the compost tea through that. I imagine the right kind of silkscreen would do it. Pretty cost effective since you can blast it with a hose to clean it.

I can't imagine how this filter would remove anything that can help your plants, no microbes, no nutrients.
What I was hinting at was that irrigation system are built to be used with fully soluble fertilizers. And that if you like to use one with something that has more particulate matter in it you need more filtering, not less.

Several stages where you filter out large particulate matter, grain size and then finally your normal filter that comes with the setup.

UPDATE!

Two of my cuttings rooted nicely within the week. I have two still in the process of rooting, and two kicked it, but probably because I was a bit sloppy on where I took them from. The good news is that I have two clones in my DWC system that have been doing fine since the 11th. No nutes yet, but that will happen soon. I have a grow log of them on the front page that I will keep updating.
