Thanks home.grower! Its down to two plants now but one of them is spreading out all over the hut so it still should be a good yield anyway - assuming they survive till harvest. I'm starting to wonder if me & hydro are like weedhound & soil - everything that can go wrong does!

So after finding that dropping pH can be associated with root rot, and reading a post from another thread, I dosed my PPP pretty heavy with h202 Saturday night - a quart of 3% in my 12 gallon system. It may have been a little too much. The pH immediately quit fluctuating and stayed rock steady the entire light cycle.

I was nervous about it and could hardly wait till next lights on to see how it took it... when they came on, she looked mostly fine but some smaller leaves at the main tops have curled down and look stressed. Overall the plant looks pretty healthy but I hope I didn't burn the root hairs too much. I did a res change last night and there was more sediment & crap in it than usual. The pH remains dead-on so at least something positive resulted. Will see how it goes. These pics are 48 hrs since the h202.

Here are a couple of pics. First 3 are the PPP and the others are of the fat little TroubleMaker Kush.
