Hey FI,i make like an organic starter coco using worm castings alfalfa and kelp meal.After mixing it sits and "cooks" for 30 days to allow the microbes and bacteria in worm castings to process what ive put in,into a plant edible form.So i might have enough nutes in my coco for a week or 2,thats the only reason i feed phd water only.
Is .80ec equal to 400ppm?
Yes I think so
