Ah..
Well I know you know your stuff DutchPimp, and that makes sense. I am pretty sure I have read that before too. PH runoff that high in soil just caught me a little off guard, my Amish buddies limited experience has only been with soil that had significantly dropped ph. I bet you and veggi have already answered my question then. Just for shits and giggles I am going to test runoff with just perlite thought to see tomorrow, I will post my unspectacular findings.
Assuming it is the soil, then the soil ph is sitting at about 7 even? (Water in @ 6.75, runoff out @ 7.25?) Is that right? If true then the water needs to be going in @ 6.5 then, assuming the runoff comes out at that point @ 7.0, then my soil would be at 6.8ish? Is that reasonable, and ok with very young plants? Thanks again for the input.

My Amish friend has some babies in 16oz keg cups, they look great, and are still in the "seedling" stage of life. All is well, however, when watering with RO water, adjusted to 6.8, (and even down to 6.7) the ph of the runoff still comes out at roughly 7.2-7.28? The soil is foxfarm lightwarrior, and the very bottom inch or two is solid perlite. (Hoping to aide drainage although the fflw is very light and seems pretty Rating: 5
