I have 2 plants and one was heavily affected and the other one hardly affected at all.

Hmmm... approx a week after I had this problem. My plants started to lose their odour. So I switched from feeding 2 days on 1 day off, to feeding every other day. This didn't seem to have any affect on the leaf problems but my ladies started to stink within 2 days of me decreasing the feeding. So you may be right in thinking that decreasing food might help. I have no way of checking my PH atm so I can't give any insight on that front.

I am really glad I spotted your threads on this, this has given me more of an insight into what caused this problem. :thumbsup: If it eases your mind any, I had this issue during flowering and it doesn't seem to have affected my girls too much. The buds are getting fat and they sparkle like a mirror ball.
