Growing 5 auto's in grow buckets for the first time ever with both

Yes and mine does as well. Two EC’s and then the PPM readout. I also use the HM Digital brand for my EC/PPM meter. It’s at least 15 years old.

Mine doesn’t automatically switch between the modes…but you can manually cycle through the three EC and PPM readings while you are using it.
