that is the ppm with the calm mag+ and the Hygrozyme and the Pot of Gold, and Liquad Karma also. is 300 just with the nuts or everything? I am useing Botanicare- Pureblend and Power Plant.

I am useing rockwool for my medium, wouldn't this itself raise my PPM the first week or so? when I started out my PPM was only 600PPM and I have not added any nuts. I did soak it and condition it, but I would think you could not rise out all the small rock dust unless you took hours and hours of rinseing.

I mixed my nuts and everything at about 25-35% strength. Nuts at 25%
