The standard conversion scale is the 700 scale (or .7 scale, same thing). Because of the 3 different ppm scales, I only use EC as my measurement. It solves a lot of issues and I recommend doing the same.

DWC PPM First feed I used rainwater with ppm of 15-18 and mixed 8 gallons with 18 ml of GHE Bloom, Gro and Micro with 4 ml of CalMag. Both buckets have new PPM of 350-390. Is that too aggressive for day 9? Or can I push more? New to DWC and growing and hoping for some applied knowledge. Thanks

Compensating for Effect of Supplements on PPM I decided that my girls probably had a calcium deficiency from using distilled water. I added a cal/mag supplement and an enzyme supplement. Now my PPM is through the roof. Should I reduce nutrient levels so that I'm still in the desired PPM range?
