I had some plants going when my care package from BPN arrived. That was the Tenth of August. It isn't a fair test, because these plants were raised in Mirical gro, Epsom salt and PLASTER. Plaster doesn't dissolve well, so, CALCIUM DEFICIENCY! Spindly stems. But ya go with what ya got. Watch carefully what Blue Planet Nutrients can do in a Month. 9-6-12
