    Coco coir ppm & nutes

    just a couple of questions as im new to coco. when doing ppm do i include the original water readings to final ppm, so my water is 200ppm so do i count this or go from zero. hope that makes sense. also when do i need to start adding nutes, a lot of conflicting views on this. a lot say...
