I believe that it takes more expertise to properly use organic fertilizers than it does for man-made chemical fertilizers. I once tried an all organic grow, but I didn't do a good job. I believe that the what I was using didn't have enough magnesium. Presently, I use the full line of FF nutes with excellent results. Regarding taste, the weed tastes pretty good. In fact, I didn't even flush, and it still tastes fine. I've tasted better, but my stuff is fine.
I like FF nutes. Fox Farm designs its soil, as well as its fertilizers especially for growing marijuana. All you have to do is make sure your pH is dialed in properly and follow the feeding schedule, and all seems to work well. Fox Farm is perfect for a beginner. I consider it a plug n' play way to grow.
