Soil is usually buffered to the correct pH. Make sure the water you're putting in is adjusted and you don't have to worry about it.

I tested the soil right out of the bag.. methinks my soil ph tester is off. I'll purchase a cheap one to compare. Thanks guys.

I've got GH ph tester drops and GH ph down... I haven't tested the run off yet. Just did an actual soil test (ph, n, p, k) and ph is 6.5
