Papa_Tanswered grow question 2 months ago It looks like she’s been slightly over fed. If it was a light issue, mostly the leaves at the top would be affected. But seeing that it’s all over the plant, my guess is too much nutrients and she’s getting a little bit of tip burn.
I wouldn’t go too crazy trying to rectify the problem. Either just give plain water at the next irrigation or dial back the nutes just a bit.
