I dont think it will be an issue, but I will be honest, I have never grown coco, or even opened my H&G nutrients. I would call them and ask. If you needed to add anything, it might be some molasses and what ever additives you may want to push them with. I suggest to anyone running all brands of nutes, to call the manufacturer with questions. They spend a bunch of money on testing their own products and I and many others get great feedback and information from calling them. Sorry I couldn't be more help.
