Promix HPCC Questions

Hey,
I just bought a bag of Promix HPCC. Looking for some tips?

I will be running Uber Nutrients which they claim
is a complete auto sensing nutrients Uni-One, Fish Shit, and I have some Vegamatrix Cal Mag.
Is there any other soil additives I should add to the mix or?
Also do I treat it like coco or ?
