@sixstring.. no you're absolutely right. Over the years I've been given a few nute formulas by some1 and was told, "this is a sure fire recipe" and I just blindly accepted that thinking, "oh, i trust this person and they must be right". For example, buying Cutting Edge 1gal bottles of Plant Amp and UJB - which are like $100 each. I didnt even know WTF they were doing, I was just naively going along. That is why I'm so determined to just sort of rip out all the old "fixtures" in my brain, and almost start over, so to speak. I've done about 4 yrs of soil grow, and really never been satisfied with my yields. Granted I've made my share of mistakes (who doesnt), but damn, its gotten old being disappointed over and over - yah know? Plus being told that this "method" works in other setups, but not mine, I just felt stupid and incompetent.. now I'm realizing THAT person is the one that is incompetent and full of BS trying to pass off the fact that there would be identical similarities and variables across the board. NOT SO!
the Canna nutes are no really no less expensive than some of the Cutting Edge nutes I just referenced. the A/B combo alone for the larger container is also $100.. The rhizo is like $60.. the PK 13/14 is another $60.. you get my drift. then I start looking at this Jack's Classic and how cheap it is.. and my jaw just drops. I'm just surprised there is no dealer for JR Peters here in Bay Area.
