More updates on pH. My coco was around 6.6-6.8 yesterday and is still in that range today. Double checked res, and it's 5.9-6.0. Both pot bases are reading consistent around pH6.1 and 330 ppm, so it doesn't seem to be anything localized (was thinking maybe algae) to my reservoir-> pots.
Also of note: It was the first time I really took the pots out of the bases. There are roots everywhere, and they look great. Also unfortunately discovered one really dead leaf on the bottom of Grape, so it seems this problem is mutual between them. It seems the high medium pH is my issue; although I am not sure if it's the root problem or a symptom of something else.
Anyway, I'm thinking a flush is in their near future. Probably today. I'll set up some pH 6.0 flush that's a mix of RO water, 150ppm calmag, and 150ppm flower nutes. Hoping to bring the pH down; then monitor to see if it holds.
My buffer process was to rinse, sift, buffer (8 hour soak in 2x calmag solution), rinse, re-buffer (another 8 hour soak) and then leave sitting to air dry for a couple days. Wondering if there wasn't excess calmag in the medium since I didn't really rinse after that second soak. The coco would've been saturated with it, and in conjunction with relatively low feeding (ppm) might've deterred the medium pH from lowering with feeds. That's my theory for now, but we'll see what the flush does.
