Ive had a ph probe running on my hydros for a bit over a month now. When I first installed it i calibrated with 7.01 and 10 ph solutions. It started out around 8-8.2 with daily fluctuations around there.
I noticed the pH would start to creep and was reaching up to 8.6 within like 3-4 weeks. I thought maybe rising temps as its been HOT here were affecting it but even having the AC running all day didnt change anything so I recalibrated the probe and it brought the pH back down to 8.2 readings again.
Well its been less than a week since recalibration and my highs are already reaching 8.5 pH at the end of the day. Has anyone run into issues with these pinpoint probes losing calibration this quickly? Is this a common issue or should I replace the probe entirely?
