Has anything heard anything good about bloom booster? I happen to have some laying around...says no fert burn guaranteed, 15-30-15
miracle grow bloom booster 15-30-15 is what I have been using for about 2 months now. I'm growing in soil so I mix it by the directions (1 tbls per gallon) and giving it to my plants once a week. I have no complaints.
I don't know how 15-30-15 could guarantee no fert burn. As for me, I've been using Fox Farm Big Bloom, which is something like .01-.3-.7 and I've had no problems with it. Fox Farm Tiger Bloom is another one, which is 2-8-4.
