    The beginning of the yellowing in your photo appears to be between the veins, which is something that I commonly encounter in the top of my leaves if I don't use CalMag with my water. I don't know your soil or nutrient setup, but I need to add 5ml per gallon with every feeding based on my water and nutrients. I grow in Fox Farm Ocean Forest and Vermifire soils using tap water that has rested for 24 hours. Nutes have always been Dyna Grow.

    A buddy of mine using RO water also must use CalMag or he gets the same result.
