Folding leafs

hi i’m new grower and don’t know what to do my plants leafs are folding in to trough, small leafs on the top i know they are opening and it is normal they are unfolding but big ones are folding to. Looks like they are closing and looks like V form. Any ideas why it’s happening? And is it good or is it bad?

My guess is too much N
Are you using blurple lights?

Using Hps 600w

Look kinda droopy to me; usually a moisture issue. They may just need water but it is also a possible indicator that you need to go up in pot size.

Droopy because of too high temperature they had today. Few weeks ago upgraded pots.
