from good to horrible in one week.....

I have no idea what happened to a few of my pants. I went away over labor day for 3 days, left light on, door open and fan blowing to keep my box at the right temps. My plants had been growing great the entire grow (2.5 weeks at that point). I come back and my plants had gotten much larger and some were finally showing signs of nute deficiency (yellowing on edges of leaves). I watered monday afternoon with nutes. Found out on wed that when I add nutes to the water it lowers the PH a decent amount, so my pre-adjusted water was likely too low. I completely flushed on wed., and had not done anything yet. Now 2 plants are VERY droopy and and leaves are dying/dead and falling off. Some plants are thriving, mainly the smaller plants. The plants that are having problems were my best growing plants originally.

Did I over water? Its sunday now and not watering since wed. it all being under 400 watt hps (did start doing 18/6) lighting on thursday. Is it something else?

see how they are very dark green!!!?? You look like you are in the later stages of Nitrongen OVERDOSE. I would Flush for another week NO nutes.

very good suggestion!

Thats weird since I had only used nutes once so far and that was because the leaves had all started to become yellow colored. Guess I might have given too much nutes... (using grow big by fox farm).

For flushing would you say just pouring about a half gallon on each of these or just water as normal for the next week?

here are better pictures of plants no under hps lighting.

those new picture look like potassium (k) deff. I just look it up in my grow bible and thats what i leany toward as fair as that goes.

Heres what i would do. Get some wood ash or something to bring your potash up. this will raise your waters PH up so you will have to lower PH back down. They do look alittle drop maybe alittle over watered. I would wait a day or two before wattering next. Then water with the wood ash or w/e you want to use, normal water with 10percent run off. See how that works out for you

I had watered this morning because I was fairly sure they were underwatered and I have mixed results. The plants that were droopy have already perked up a bunch. Half of the plant is happy looking while the top bit still is a little droopy, likely since water hasn't had time to affect that area.

Now the comical part: with one problem solved comes another. Some of the happy plants from before are starting to look a little droopy. Looks like I am going to need to vary the watering schedule with my plants since some are needing a lot more water then others. Through all of this, only one plant has neither had overwatering/underwatering signs or nute deficiency/over nuting through this entire grow. This may be my best plant because of this. Too bad at this time I do not have room to clone.

Too much nitrogren. Check your pH, If its normal (5-6) then it could be nutes. Nute burn. Flush for next 5-7 days with non stop water and make sure all excess drains out of your soil. Add some horse dung or bat guano your plant should be better in no time.

I guess if its nitrogen overdose I'm curious why the leaves started yellowing around the edges, especially at the start when I had not used any nutes yet. Could it have been nute burn from my FFOF soil, even though they grew great the first 2.5 weeks?

EDIT: you guys are probably right with over nutes. Since I use tap water I'll have to but a filter tonight after I get off work so I can just filter the water right away and flush tonight instead of needing to let the water sit for a day or two and letting the chlorine evaporate. Damn, I guess FFOF may have too many nutes now a days and my plants just weren't big enough before to use enough of it and get nute burned... Those brita water filters enough for filtering my water? I assume it should be.

flushed all plants last night with distilled water, about 3/4 gallons each to start them off, will keep flushing all week and will lay off nutes. Still obviously discolored on the ends, but they started growing since last night and there is an obvious difference. growth really had stalled out over the week, now they are getting nice a big. ALso i've noticed my plants side branches (not the main ones, but the ones that grow when you top it) have been growing very nicely on their own without any topping and are starting to branch all the way out and become bigger then the main side branches. Not sure if that normally happens.
