It helps to let your PH range between 5.6 and 6.4. The logic behind this is the root zone will pass through the best PH for all of the various nutrient's sweet spots. Are you using Botanicare HydroGuard? I had a plant a couple of grows back that had a Cal-Mag problem that would not resolve no mater what I did. This shows that some problems may be genetic.
