I've only been practicing KNF for a few months. As a chemist, I'm checking the pH of fermented plant solutions and Indigenous MicroOrganism solutions. We use rice instead of potatoes. Both pHs dive to around 4 and stay there. When diluted for the fields they pull the applied solution pH down to 4-4.5.
I've been trying to maintain both the FPS and IMO solutions arolund pH6.5 using dilute KOH, checking ~ every 12 hours, each time the pH is down below 4.5. I adjust it back up. Now looking for similar experience and finding nothing about pH checking in JADAM / KNF.
Any ideas anyone?
