I am using light warrior with added perlite in week 4 now--my question is that I am getting ready to transplant from 20 ounce cups to 1 gallon containers. Foxfarm says its light warrior and ocean are ph bal between 6 and 7. My RO water is bal to 6.2(I use a Hanna and 7.0 sol. to make sure it's accurate). Last night I flushed the cups with 100 ounces of pure water(the water was running clear out of the cups), I collected the last 20 ounces and checked the ph---to my surprise the ph was 7-so I expected the ph to at least drop to 6.5-6.6(I ran another 100 ounces and collected the last 20-----the ph was still reading 7 on the runoff). I understand that the nuts ph rise slowly over the course of 8 hrs but expected the ph off the runoff water to drop closer to the 6.2 with all that flushing that I started with. I'm wondering if my plants are missing out on some nuts that are in the 6.2-6.5 range. Has anyone tested their flush run-off---if so what were the results?
