Well, I'm just about to go, but I was reading up on that stuff you had suggested and your guide and I've got a question, you measure everything in PPM and I guess I don't know how to convert that PPM over to some metric or standard amount to use for the nute solution. I just isn't making sense to me I suppose. I don't know if I'll be able to afford a PPM meter or not but I'll let you know when I get back this evening...it does seem like a necissary thing however..I can see the importance in it. Another thing I'd like to ask...I've got Spray-n-Grow and I was wondering how much you think I should use it? I've been doing something like once a week foliar.
