GMSgrowsanswered grow question 4 years ago I see 10 ml per gallon. And a little bloom. You really shouldn't be adding any nutes to your baby until you see signs she needs it. If your feeding by the bottle once you do, dont feed by the label or you will kill your girl. If you havent got a ph ec reader, which anyone growing should have, then feed at a little less than half what the bottle says. Cheers
