The led light is 30 inch away from the plant.Maybe too close to the light? Is it just the top leaves? Almost looks like calcium def or something.
Damn man. Thatza burn for sure .I did give a Northern Lights a potassium overdose ,which burned the crap out of it,but I'm not sure what a potassium deficiency looks like.... afraid I'm not much help here...
I'd say be careful if you end up adding more potassium to your plant's diet ...
