Howdy everyone. New grower here. 3rd grow. Learning all the way. To look back at where I started kind of makes me proud of where I’m at now. The amount of gained knowledge is amazing, but I also have a long way to go.

It seems like every time I try to educate myself regarding PPM, I come away as confused, if not more, as I was before. I just read something where a guy was chastising other people for testing PPM if you’re growing in soil. So, as I have in the past, I’ve turned to the DG community for the low down. Is tracking PPM something soil growers should consider, or is it a Hydro grower only thing? Should we do runoff or slurry test? Is there a target number or range? Will the ph be the same as before feeding? What is acceptable ph when doing these test?

This is the best forum on the internet because of you guys. Can’t thank you enough.
