Hello I'm having some root problems in a flood and drain system, my first time, and it's killing my plants one at a time, they'd roping fast. I can't get any h2o2 right now but I do have 32% calcium hypochlorite. I've already put about 4 grams in a 75 liter res and fed the plants for one 12 hour lights on cycle, but I'm wondering if I made a dunk and put the roots in it, what strength can I get away with without killing the plants? Thanks.
How much calcium hypochlorite is too much?
