Can anyone help me to diagnose what cause this yellowing leaves? My aquaponics ph is 8.2 but I have added eddha iron to the system. I even foliar spray cheated magnesium and yellowing leaves are still there.

Doesn't look like iron since the new leaves are nice and green. I was going to say magnesium but looks like you've got that covered. What have you been using for the magnesium spray, how much and how long? |

Iron would definitely be locked out with a ph that high..
