Whats wrong with these leaves?

Could somebody PLEASE tell me what's going on with my girl? 26day into 12/12.

Looks like nutrient burn to me in the second photo.

oy m8te is that the only place that's doing that?? looks like potassium deff.. if thats the only spot then just relax no worries.. maybe just brushed it with some nute solution when being watered.. KEEP ON GROWIN

The developing leaf set on my girls did this every time I fertilized em. No matter how small of dose I gave em it was like clockwork. I think your just fine mate.

Nutrient burn. It curls the ends of leaves. Stop using nutes and use pure water to flush out for a few days.
