Looking to mix my own soil similar to Bush Doctor Coco Loco

Whats up guys

So I usually grow in Bush Doctors Coco Loco, as I have had great luck with it. I enjoy it because I don't have to PH my water or feed my seedlings, just straight water for the first few weeks. I recently came into about 500 gallons of brand new Coco w/ Perlite, and I was curious if anybody had any idea how to amend this Coco to try to replicate Bush Doctor's Coco Loco.

I posted a link down below to the Bush Doctors Coco Loco for reference

Add about 20% compost or earth worm castings. Or "Happy Frog Soil Conditioner" if you want to stick to Farm Farms stuff.

Then find a balanced All -In -One dry fertilizer and add 2-3 tablespoons per gallon of soil mix. My favorite is "Down to Earth BioLive" (5-4-2). But there are lots of brands, including Fox Farm.
