Have you got leaves getting all droopy too? I can see a lot of residue on the reflective surface, what have you been spraying on the plant, and how often? More details will help us give you a better answer, it can be one of a few things.
I Sprayed it with bloom booster and that was last nite.i water it when its dry. As for nutes I never gave it much cause it was in the soil when I planted.its on 12/12 for a week now and this is the only time I gave it bloom booster.
this will help you.
IMO-She's sensitive to the nutrients. You never feed her much, so when you give her a regular dose like your bloom booster the plant can't handle it, and stresses.
Leaves curling under is a sign of over fert.
