thanks
here is a photo of my "old school" ppm meter. I called the company a while ago and asked what conversion they used, and they told me neither- and they had some proprietary algorrythm or something like that. I have bought calibration solution and can calibrate. I know the needle doesn't move at all with my RO water..Real hard water around here
anyone familiar with this? what should my baseline ppm be before i add the nutes to get the optimal level?
Im also using FFOF soil, and was going to feed every other watering to keep salt buildup to a minimum..
