Stonerdanswered grow question 4 years ago The leaf damage doesn't seem out of the ordinary, probably just some damage caused by someone handling her.
But from looking at your plant it seems she has a severe Nitrogen (N) Toxicity - Dark green, clawing foliage with tip chlorosis (burns)
Try lowering your A & B fertilizers to about 2-3ml/l and keep a close eye on your plant to see if the leaves get lights in color, if dark foliage persists lower it to about 1-1.5ml/l
Hope this helps! Good luck and happy growing :)
