NL problems, Pics, help?!

Have a leaf curling issue, not sure what's up. Any help would be great!! It's only on 2 plants which happen to be the northern light strains. Into the second week of flowering, watering the same as the rest, only these two have the problem. Some curl up and some curl down..... ??

looks like overwatering....

that's my thought but the ones that are curling up threw me off of that direction.

Looks like they aren't getting enough light.
