I think pH up and down are organic by default because it is natural, but I could be wrong. Also, 6.3 is pretty high for your pH. Optimal pH is around 5.7 or so. I like to keep mine right around 5.8. Using lemon juice is going to get expensive fast.

If I were to grow cannabis, I would only do so to supply myself and my close friends. Doing this would take myself and my friends out of harms way by knowing the source of our cannabis, as well as take hundreds of thousands of dollars off the black market annually. It would also lower the demand of black market cannabis, and would ultimately help keep cannabis out of the hands of minors.
