Looks like over watering or heat stress to me. Whens the last time you watered and whats the temp looking like? Also are the leaves brown and crispy can't really tell, and are you spraying the leaves with the lights on?

2000w??? Wow, seems like overkill to me at this stage, seedlings and young plants don't need that kinda light just yet and yeah, heat stress could be an issue. Just make sure there's plenty of distance between them and the light, when you put your hand at plant height, you don't want to feel too much heat. How are your temps, anything above 85f. is going to start to affect growth? 40% humidity is fine, it can get up into the 50's no problem, although lately I've been having problems with a leaf fungus when I let it get that high so I keep mine between 35-40%rH.
Also don't foliar feed under intense light, and I personally don't anymore, just seems to cause more problems and watering the roots seems to be enough, imo. Finally, aside from it being part of the natural cycle, it seems to me that my girls just look better when I give them a nap during veg, so except during the seedling stage which I do run 24/7, I don't go over 18 hrs of light (plus saves 25% on your light bill ;?).

Well really I'd look at how many plants you have and how much space you need at each stage. For instance if you have 10 young plants in 6" pots, you could fit them all under one 400w light easily, but then when they're transplanted to say 12" pots and they need more spacing between then I'd step up the lights to 2x600w perhaps. Are you using 1000w's?

I know a lot of growers who use 1k lights and some that have moved away from them back to 600w as more efficient and cooler. I also read somewhere that 600w are supposed to be better overall, but not sure if that's backed up by scientific fact or studies. I have a couple 1k ballasts, but after a couple of grows i decided to switch back to 600w, but rather than buy more ballasts I got a couple of those Sunpulse Sunsplitter's that allow you to run two 600w lights from each ballast, works like a champ for me ;?D
