I bought a EC/PH handheld meter from Hanna and I recalibrated it using the provided solutions. My ph was set correctly and using the EC solution it registered what the package said should be the correct number.
I read this forum a lot and everyone always uses PPM when referring to the amount of nutrients they use. This causes me some concern because when I used my ppm scale on the meter in the test solution it didn't read near the 1500 ppm I assumed that it was going to read. HOWEVER it did read the right ph level and ec level in their respective solutions. So reading further through the manual that comes along with the meter it says that there is no calibration for PPM that calibrating it using the EC calibration method adjusts for the correct PPM. Hence my problem, if the EC is correctly calibrated then why doesn't it read the correct 1500ppm with the solution that I got.
So I brought the meter back to my hydro store and he explained to me that was the way it worked and that I should be using EC to properly adjust my nutes.
So that being the case can someone give me some insight on this and if it is the case is there a proper schedule of nutes per week that I should use in EC and not PPM?
