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.

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.4 years ago

White mold?My smart pot is turning white at the bottom. There also appears to be roots trying to pop through. I put rocks between the pot and plate for air. I have one blade of grass and a tiny weed popping up, so conditions at the top of the pot are okay. Should be worried?

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
