Please tell me you don't test the ppm's after "fertilizing" the toilet water??? Hahahahahahahahahahahahahahaaaa...... Sorry, just couldn't help myself............

I think your over analyzing the ppm and ph.... As long as you can keep your soil in the proper nutrient range, and as long as your plants are growing fine, then you should be fine.... The ppm's of runoff are crazy high because of the very fine soil particles that are also present, it's not just reading nutes....
