Hawaiian Flower Magic 9-18-9 "Use on all indoor and outdoor flower, orchids, plants and vegetables" it says on the front. 8 drops per quart of tepid water. I panted my seed june 4th. It is currently 22" in height and I'm starting 12/12 cycles now. Is this plant food good for Marijuana? If not do I NEED plant food and if so what do I use?
