Hey, bro! :wave: Your girl has already shown her sex and is flowering, right now she really needs phosphorus and hardly any nitrogen, the tips of the leaves indicate a slight phosphorus deficiency! You don't see any symptoms with the element blocking feeding, so you just need to slightly increase the phosphorus in the feeding (bloom additive). She will recover quickly and the deficiency won't show in the new leaves! :ok_hand::innocent::+1: Good luck, bro! :wave:
