Hello, I am using a top drip recirculating system, with coco fiber medium, and House and Garden nutrients. I apply my nutes to clean quality water, I adjust the pH to 5.6 - 5.8, then I water twice a day for 10 min. My problem is that I can't seem to keep my pH down. It rises almost 1.0 a day. What can I do to keep this down?
