Your roots may be drying or waterlogged

you may be losing nitrogen in your leafs( Light green, with tan/yellow tips)

no yellow yet. just getting a light green from the inner part to the outter. and i doubt its N, i use some bomb nutrients. and doubtful on the water log i dont water them enough. i actually like to deprive them sometimes. also. its not happening to all my strains. only some of them.(my indicas)

Calcium/magensium may be an issue

as well as ph.

I'm not stating these are the reasons for your curls, you should just check these variables to determine your plants needs
