a little more info about the set-up and the nutrients and medium would be a bit more helpful,but i'm guessing that it's a pH problem,try to adjust to about 5.5-5.8....bonbon
bonbon Reviewed by bonbon on . HELP! HELP! HELP! :eek: :eek: HELP ME!! My plant is getting these brown spots on its leaves. They are occuring on the edges of the leaves as well as near the veins of the leaves. I looked it up and it looks like a potassium deficiency. So i uped my hydroponic solution with the highest potassium concentration (florabloom) yesterday and nothing has happened. it looks worse and worse as time goes by. I am on a 24/0 light cycle.
