Your high source water pH may be from a high mineral content; if you have not watered to the point of runoff recently, I'd do that to help clear out any buildup in the soil, making up your fert solution at 7.0 to just SLIGHTLY raise the runoff pH. Water until a significant amount comes out the holes, and go back to your normal schedule, making sure that there is a gallon of soil per foot of main stem.
