Chronicdom

I have been growing with T Rex super soil and using their Nutrients. I’ve had good results but want more control over nutrients. I want to switch to Coco. It’s pretty much impossible to get big brand names here for pre made bag or bricks with a name brand I trust. Does anyone have a quality source they use? Also what nutrients have you found to be effective in Coco? Im debating using AN, Canna or GH.
