Hey ya’ll so I finally got my PPM tester and I understand how it works with measuring the ions in the water from all other variables besides h2o but i dont understand why we do it? So i took some tap water and it measures at 109.
Sorry the pic is hard to see. Then I added some PH Down. My water from tap is usually 7.4ish. I remeasured and got 138 PPM
So am I in a good range? I gave my plants there first feed Sunday, some Bergmans seedling fertilizer. I got a journal going on the grow if yall are interested, greatly appreciate any feedback!
