My guess is your EC meter does not go to 2 decimal places. PPM is just EC converted.
Just to clarify you have an EC of 0.04 and a PPM(500 scale) of 20.
No you do not need an RO system. My RDWC grows have all been with tap water of 180ppm(500 scale) EC 0.36.

noticed the ph in the Pots is at 6.5+, something to do with the Hydroton. In order to balance it i had to drop the res PH to 4.0, but it constantly rises back up to 6. Using RO water
Suggestions appreciated, will the Hydroton eventually stop having the ability to raise my PH?Week 1

Lightening Soil - Coco Coir or Perlite?I think my soil is a bit heavy and could have better drainage. Should I add more perlite or some coco coir for my next garden? My base is Biobizz Light-Mix. I'm thinking of supplementing it with 10%-15% of perlite or coco coir. Does this sound good or should I do something else?Week 10

First time testing PPM and slightly panicked :cRunoff was at 2200PPM. I flushed her with 5L of pH 5.8 water. I got the runoff to 1000PPM where I left it. The pH was at 7 though and was higher than before the flush. Why is that? I always pH before watering. Also, is the flush going to cause trouble for her? I kind of panicked.5 years ago
