Bro, after reading it. It's looks like using that will be better in soil. I know it says works in any sub but with all those great organic and soil boosters you'll be wasting it in coco colr. Look like top stuff for soil. But with coco it'll be just like passing any nute that's decent in coco. For no no brainer go with soil it's meant to be soil, well it'll give the most benefit for soil and it'll make the taste better as that's the whole point or more what that nute is pointed towards quality not quantity. Idk though that's just what I've read from it, soil will be the way to go. Or if using coco just go with a cheaper hydroponic line. Happy growing.
