Right here -a reason to start with a good solid soil that is of known pH and contains enough composted humus to HOLD.

My pH problems ended immediately when I switched to humus as a base for my mix. I eventually just gave up even checking because no matter what I did, the pH stayed constant.

Chrissy you already transplanted but I would have suggested at transplant time making an extra effort to leach out the existing soil, and then go to a very very good quality compost for the transplant.
