Also Jerel, do you use plant sap pH as a metric for plant health? There is a lot of talk about this in the regenerative circles, but very hard to find solid resources or research papers on the subject. New meters such as the HORIBA Laquatwin pH meter allows to measure pH with 0.1ml on the spot. I am also curious as to whether its a useful metric – maybe sap pH levels change when its already possible to see problems visually on the plant, unlike the NCC sap analysis which gives us a few weeks of headway.
