Hi,
I have PH indicator drops and that simple PH meter with one node that does not need calibration.
Big difference in readings. Drops are like a year old... would that impact the way they work?
Should meter at all be used to measure water PH?
I have AD12 coming in next week but still... seeds where planted today and i don't want to do any damage.
