Mutt, yes $$ an issue right now ($1K tranny repair didn't help...lol), but I'll look for the fert you mentioned. Googling it I found their "Schultz Bloom Plus" (10-60-10) is that the one you mean? The reason for going with their Cactus Plus is that it was low N and higher in the P and K, but weak enough so I wouldn't burn my babies as I've done previously with MG.
