I just scored 1/2 pallet of biobizz coco on the super cheap. I've never used coco before, but I do know to do a runoff test on anything I'm thinking of planting in. Saturating with ~0ppm RO water gives me an initial runoff of ~600ppm. Can I safely assume this is all Na and K, and that I want it OUT?
Running double the pots' volume of RO through gets me ~25ppm runoff on my tester pot. If I flush all my pots this way at the start, should I be safe to proceed with regular feedings plus ca/mg from there? If not, what?
