Medicine for pH Drift
I’m epileptic, manic-depressive, and have paranoia problems. After I found that marijuana helps me, I quit taking prescriptions and now suffer no side effects. This amazing plant was put on earth to heal all people, and it has helped me. In an effort to improve on the black-market pot I used to buy, I started growing my own organic plants. I was growing in soil with Age Old Organics and Thrive Alive, but the fungus gnats and spider mites were getting to my plants. I changed to an ebb-and-flow system and use hydroculture clay balls in 6-inch pots. I keep the pH at 5.8. My problem is that the pH jumps to 7.5 after two days and to 8.7 after four days. What’s going on?

Age Old Organics is full of bacteria, either aerobic or anaerobic. Aerobic bacteria need the oxygen in air to live, while anaerobic bacteria thrive in the absence of oxygen. When the nutrient is diluted into water, bacteria multiply and need oxygen to survive and flourish. It sounds like your plants don’t get enough oxygen, so you’ll have to add it to the nutrient reservoir mix. Use an air stone or two attached to an exterior pump that takes in air and disperses it into the nutrient solution. You might want to try a new organic fertilizer, Formula X (available at gtghydroponics.com). It’ll help you with these problems.
