The coco is probably added just as a soil conditioner, I do the same with my soil, about 10% coco give or take, doesnt interfere with PH and messes up with nutrients that way. Im pretty sure by looking at the ammendments that it has very little coco. Im also uncertain if this is good to start from seed, might be too hot, depends mostly on how many nutes are already available from those ammendments. I do my own super soil but thats a pretty solid mix, the only thing I dont like is the blood meal but its just personal preference, its a good source of nitrogen, its just that antibiotics and animal hormones can acccumulate in blood meal if the source is an industrial farm.
