Oh wait, r u asking if u can use coco nutes in soiless mix? Yes. Coco nutes just add extra things the soil would already have in it. U can do the opposite too. Use regular nutes with Coco, you'll just need to
add some things.
so i could use roots 707 formula with some perlite and worm casting as a soilless mix & maybe i can throw in some more coco, using canna coco nutrients a&B for nutes with pk 13/14 during flower?
