Ph meter problem

[El Gusanito]

Hi
looked at the end of the ph meter milwaukee 600 had lots of builg up so soaked in CLR for a few minutes then rinsed in fresh water used a Q tip to clean build up then rinsed again. Pulled out the test solution to caliberate and no way it would only go 5.7 at the top and 4.6 on the bottom. What happened?
Did Mongo do BAD?
let me know your ideas.
Of course it's at lights on 6pm and the hydro shop is closed.
Hopefully i will not have a ph spike.

Same here. I go thru THAT particular meter in about 2 grows. I think it's the sensor on the bottom. It says you can pull out the wick a bit and renew it, but I havent been able to do that. Best bet is a new one...luck!!!!!!!!!!!!!!
