thanks bwd! was hopin I'd get a response from you. I'll probably get some pH down before Sunday water, it's just one of those things that you can easily spend 5-10x the money on a "solution" at a hydro store, when you could just as easily figure out what's in it and spend pennies. A friend of mine had to spray his plants and the guy told him just mix a certain type of dish soap with water and you have the same shit, at a fraction of the cost.

Beware these super-upcharged products!
