I buy the powdered blackstrap from amazonia, I'll look for links and wal mart epsom, plain, nothin in em. I think I got it memorized now, per gallon its six tbs of epsom to one tbs blackstrap. Ive juiced it up once or twice, but can't tell much diff, so I keep with that recipe. Basically a tbs per gallon of this mixture every watering and I just keep using it and noticing what I notice, but it is cheaper than sweet, and to be honest, if you see what is in FlawlessFinish, thats the same basically as adding a bunch of epsom only last week, if I remember correctly, without double checking. I also use MC BE these last two rounds with my natural sweet with whatever is in that powdered blackstrap and I have no ill effects whatsoever. Whats ironic to me is I use URB and most of the stuff mentioned above that is in Sweet Candy is also mentioned being in the URB, as far as microbes, amino acids, etc. I use URB every watering. I do know if your water is too hot you kill a lot of good stuff in the molasses, etc. Not all.
