OK. Perhaps the results I am getting have to do with the way I set up my gorw medium? I started out with river rocks covering the bottom of the pot, followed by a fine sand to cover the tops of the rocks, followed by Organicare plant nutrient and topped off by Fox Farms Ocean Forest soil.

Am guessing here, but is is possible that the sand and the river rocks can change the pH of the run-off? When I have poured clean water into the medium and I examine the run-off there are fine sand particles present when I take my sample for the pH test.

In any event, I will take your advice Irydyum and follow StinkyAttics guidelines for getting proper pH readings and then post them here.

Thank you!
