Amnesia Auto Aquaponics

Been slowly removing leaves to allow light to enter flowers nearest the main stem. Still only been watering the basket with nutes and been adding straight RO water to the tank itself. My pH meter had been off by +.5 so that messed things up a little too. Rookie mistake, I bought the meter about a month ago and just calibrated it. No foliar sprays, no need oil, just a fan to keep air circulating. Pistils are almost 50% orange so doing a partial drainage off the tank and straight water from the end of the week and for the remaining week or two ahead.
