Re: Leaf question ?
I was looking locally for some Nytrozyme myself as I want to have some on hand. I just read up on it and yes, it sounds like a great formula.
Also, if not Nytrozyme, look into Liquid Light... they are pretty much the same thing, or, for the same purpose anyways.
I also concur w/Bluedog on the N deficiency, try a lil of something high in N... that's a good place to start... good luck M8!
