Got a shopping list of nutes I should have on hand?

Also, is my logic below right....


Right now my water PH is 8.4 and my soil PH is probably somewhere in the low 5 range. The combination of the two is resulting in run off water of 6.8.

As I add more water at 8.4 it will leave some of its alkali properties in the soil, resulting in a higher PH of the soil. The higher soil PH will result in a higher runoff PH.


As this happens, should I be lowering the PH of my water so that I continue to get 6.8 on the runoff?
