In watching the latest updates on the app it hot me thinking ,how often do we all really check our ppm ec ph pens for calibration....
In honesty I used to have a set monthly regime, we recently moved and as u guess everything's all over the place.
I last checked mine 2 months ago 😢 letting ma game slide there.

Also do u all have different sweet spots for different strains ?
Toke on peeps
I had a quick look online and found a pen that did both called Aqua Master P160 Pro - pH EC PPM TDS Temp Combo Meter and I think am going to try it out. Here is a video of it https://youtu.be/RIqaOkp0cBk
