So I have a blue labs pen for ph. It’s generally awesome but I got a case of root rot this week and all the sudden the pen starts going crazy.
pH:
6.1
5.5
7.3
All within seconds. So I recal the pen. Good as new. Check for 7 and then 4 after calibration. Perfect. Go back to buckets same deal-all...
Hey y’all, any help would appreciated!
first time in DWC.
RO water
Ph 5.8-6.1
Fox farm nute trio (at about 1/2 power)
Cal mag
the problem is worse on lower leaves but pretty random
