Sorry, I do not recommend any MG products for the growth of cannabis...these are chemically based nutes and while you grow great looking meds with them, they stay in you meds, will not properly flush out of your medium and you end up with chemical tasting meds. I've been at this a few years and find that simple organic nutes are the best (bat guano's and fish emulsions). I like good tasting medicine, no compromises here!
Peace...j.b.
