pH calibration reminder

[RobM]

To all other new growers remember to recalibrate you pH meter from time to time. I did 2 feeds with it being .8 to high. .. (in mid flower none the less)

anywaya just a reminder

good morn RobMyou are correct any time my ph is out of range the first thing I do is check the calibration ,all it takes is thinking your ph is at 6 when its really at 4 .

Luckily my pH pen reminds me

Thats a thing? What brand etc?

Made by BlueLab. It’s digital readout has a pH checked or not checked. When not checked time to cAlibrate....you can’t miss it.
not a cheap item but worth it.
