Grow Mediums New to coco grow

[flynfish]

Hey all I am moving from soil to soiless growing. I bought this bag of coco and was wanting some opinions on it. Will be growing 2 blueberry bliss under a 96*3 led in 3 gal smartpots. Will be using the gh 3 part nutes. Is there anything I am missing like do I need some calmag. Any help is always appreciated thanks

Have cal an mag on hand. Seperate if possible. Is my preference. But get some. That coco should work just fine. Bit fancy too.
