hi everyone, i have 5 plants in coco with 2 weeks left to harvest, been feeding them G.H nutrients, i'm gonna stop the nutes for the last 2 weeks, i've been told that feeding blackstrap will help em in the last two weeks, i've gotten hold of some organic blackstrap only thing is i'm not sure what dosage to give em or if it's a good idea at all, any input greatly appreciated, cheers.
