Hey there, bro! 👋 Your girl has already shown her sex and is flowering, right now she really needs phosphorus and practically no nitrogen, the tips of the leaves indicate a slight phosphorus deficiency! You don't see any symptoms with the element blocking in your feeding, so you just need to slightly increase the phosphorus in the feed (bloom additive). She'll recover quickly and the deficiency won't show in the new leaves! 👌😇👍 Good luck, bro! 👋
