I am about to pull out my teeth if I can not figure this out. I have a drain and fill setup, 150watt hps, 5.8-5.9ph level, using distilled water with advanced nutri, feeding 3X while lights on. She is also in flowering for 5 wks so I do not know what I can spray. She looked beautiful until about a week ago. The tips started turning brown on the upper fan leaves. Then the lower leaves started to get brown tips and curl under as well. I did adjust the feeding because I thought I was over fertilizing. Now brown spots are appearing on some of the leaves. I also just noticed that the roots that are towards the outside of the res have white fungus. I do not know what to do for this either. Its not a lot but I know that it can spread quickly so I need advice. I attached a few pictures. Please help, I usually get good advice from forums here and I hope this time is the same I do not know what else to do.
