Growing question. Leaves turned in.

[Rusty Trichome]

I am trying to grow a couple med plants. They both grew well indoors under flouresnet bulbs. They are both about 4 weeks old and a foot or so tall with nice indica wide leaves and dark green.

However about a week ago I noticed leaves are folding over downward on many and there are not spots or color differances. Just folding over leaves.

I am not over or underwatering and am feeding to plan.

Any ideas?

Would be a good idea to copy-n-paste the troubleshooting form (there's a link in my signature) here, and fill it out as completely as possible.

Sounds like a ph or rootbound issue, but filling-out the form will likely get you a more accurate diagnosis.
