Grow Mediums pro mix and mykos advise needed

[hello]

I wanted to try pro mix HP or other, and mykos but I am confused on what or if I need to add to this. There doesn't seem to be any nutrients in these two items. I am confused. Thanks for any help.

That is correct. Pro Mix HP has little in the way of nutrients to start. Normal fertilization with a good line of nutrients for cannabis is required.
