So, you don't think it's a nute def.?
The PH up stuff is pretty wicked, I spilt some on my concrete floor and it basically bleached it. That's the only thing I've changed too. My nutes are the 3 part series GH and I've been in the bloom phase now for the past week. I've added the PH up maybe 3 days ago.
