I use to use coco, just wasn’t for me. I use promix hp with the mycorrhizae in it. I also use terp tea grow and bloom as my amendments. Gaia Green has some killer amendments, but it’s hard to get. I don’t bottle feed anymore, too much time and effort, I got tired of it, or lazy, however you choose to see it. I just ph my water and that’s it. Use the grow amendment during veg, and top dress with the bloom during flower, easy as that. No over fertilizing, no guess work, just let it do what it does.
