Aww. That doesn't seem fair. I don't check ppm oon my container planre, and they look fine. With regard to that pH chart, I strife for 5.5 fr hydroponics, and would look at the ye chart more closely if was having problems I could identify as related to nutrients. Sometimes, the less I know the better.
