yeah, there's a few of those recipes available crop specific to growing weed. I use GH Floranova series. I think GH created Floranova for marijuana growers. Some of it's marketing strategy is obvious that it is intended for indoor cultivation of marijuana. THere's a little more in it than the 3-part, stuff beneficial to marijuana in particular. The way they recomend using it, and when, is the exact same life cycle of marijuana plants. I'm willing to bet that about 25% of GH's sales is from home growers of marijuana, maybe more.
