At one point in time, I concerned myself greatly with runoff ppm and ph. I too was extremely confused by my readings.
Then I stopped doing it. It was exhausting and crazy.
Now, I never do it, and I'm extremely happy and growing wonderful things.
I'd love to help in some technical way, but can offer no such help.
I look at my plant. If the brand new growth is bright green, I dose her slightly higher. If it's coming out too dark green, I lighten the mix. Works great for me. PH to 5.5 - 5.6. KISS.
