Transplanted from aero cloner to 3 gal flood and drain system with a hydroton medium and general hydroponics nute line. Ppms are 600, ph is 5.8, and water temp is 67F. Plants have some odd cupping that looks like maybe over watering but also some weird spot that seem like a calcium deficiency. Was hoping for some insight. I’m using tap water and haven’t added any cal mag in because I heard that tap water levels were supposed to be higher naturally but looks like I might need some.
