Strange looking plants... (pics)

[redsunknight]

So about 2 weeks ago I noticed that two plants in grow closet #1 were growing very strangely. I thought that maybe it was heat stress, so I promptly removed the tinfoil that I had neglected to take out from both closets, and I kept watering them every two days. Since then, I have found 3 more plants in the second grow closet that were doing the same thing, and I cant figure out what is causing it! The temps inside the first closet is around 80, and the second is around 75. Any ideas?

(The first pic is from about 2 weeks ago, the other two are from today)

Meh, they do that. I've cloned and topped a lot of plants and many of them go all weird, but usually straighten out.

They are from seed and none of them have been topped

i had the same problem with hydro, because i was watering one side and not the other so it was un evenly growing

I just started using fox farm big bloom, but I haven't used any ferts until now. And I have yet to invest in a Ph tester...
