Can't figure out what this seedling is doing?

[pointer80]

Hello all, First off if this is in the wrong place please move. I have some seedlings that are about 16 days old and are looking good but I have one that is confusing the heck out of me. I have a strawberry eclair strain that started drooping and leaves started curling up like it was being over watered so I left it alone and the next day it perked up and looked great. That evening it started doing the same thing as far as drooping and curling. The next day it looked great again, and that evening it drooped again. The next day the same thing happened. These are in a grow tent under 315 cmh lights with around 50% humidity and about 75 to 78 degrees at all times. I am very confused why this keeps happening every evening? Any help would be appreciated. Thanks all.

Leaves move alot throughout the day. They look healthy. I wouldn't worry. You'll need to transplant soon though.

I agree. You should transplant.
Probably getting rootbound.

Transplant and under watered.
