I haven't started really shopping around or comparing brands, but I am currently using General Organics CalMag
I'll take a look at their lines as well, thanks brother!
I hear really good stuff about House and Garden,, I might give it a runon a few plants this summer,, if I can get a sample to try... working on that. I've also heard good about General Organics, that is another line I've considered. As much as I want to grow all organic, or not from the bottle,, I also want to try as much as possible. Good luck with your decision.
