So I have read about 1 million recipes so far, and I am getting some good ideas of what I am wanting to do. I have been using Fox Farm products thus far, but would like to start making my own. I am not looking for any recipes per se I am just wanting to know if there are certain things that I should not use along with certain things I should not mix together. Basically if you have fucked up a mixture I would like to know how it ended up that way so that I do not make the same mistake.
