Coco needs to be fed daily at a specific pH range of 5.8-6.0.

I grow coco and it’s a little bit of a learning process. Buy a ph meter to check your water, most important. Also, you need to feed nutrients with coco, as the medium doesn’t really hold onto anything. If your coco wasn’t buffered when you bought it, you need to add cal/mag to it prior to growing, and throughout the grow. tons of info on the net (rabbit hole) but check in to buffering; ph monitoring with coco; rinsing coco before growing (I think the Most Important)
