It may sound odd but I just don't get into the chemistry of bud that much, I know what I like in my smoke and have found the range of clear and cloudy best suited for my high in sativas. I do however get more into the chemistry of my soil and its relationship to my plant. According to many of the young people on here I am just too old school in growing, but hey to each their own, I know that when my soil is right that I don't believe that you need anything else. Hell, the plant can only take up so much stuff and a good composted soil has everything in it you need.......some extra teas now and then are great depending on the strain. I know I can't always go like that if a strain is an especially heavy feeder, but then I tend not growing that strain again, just me.
