Mike, any ideas where locally to get a pH reader in a pinch? My hydro shop is closed until Monday. I couldn't get anything to balance tonight, then tried calibrating and found it went out of whack again almost immediately after calibrating. I'm afraid to water now without being able to balance, and afraid I won't put my hands on a pH pen until Monday.
That sucks. If you are always mixing the same amount you should have a good enough idea to get you in the green zone for a day or so. For instance if I mix my regular flower nutes I know I need 4ml of ph up. Almost right on 5.78 every time.
