Cal/mag issues … or it could be PH being off which is causing the cal/mag lockout
Hey @Michael_B,
The Champs @SilverGrobo and @chris_barfield have it right, I suspect your pH probe needs cleaning or calibrating, so check there 1st. If all is good, reach out to me on our support@grobo.io channel and we can investigate further.
Cheers,
Stephen
