Ok guys this is a dumb question but I'm not exactly sure how to read my meter. The guy at the garden store that sold it to me didn't seem to know much more than I. I have a brand new Bluelab truncheon. It has one row of lights and 4 scales on it. The scales are ppm (ec X 700),cf, ec, and ppm (ec X 500). The meter is working fine I just don't know which ppm to use? The ppm (ec X700) has a scale from 140 up to 2520, cf is 2 to 36, ec is .2 to 3.6 and ppm (ec x 500) is from 100 to 1800. I just took a reading and the light flassed at 1120, 16, 1.6 and 800. What is my ppm? I'm growing tomatoes and having some problems. Any advice?
