coco isn't magic.. it's simple an inert medium that generally holds less water than other options - neither good or bad, just is. This is why you need less perlite in it to reach a proper gas:water mix pervolume (33% vs 50% perlite)
simple treat it like any other soilless medium... essentially like hydro in a lot of ways, except there is a physical medium. Full diet, every irrigation with fertilizer that is 100% soluble and 100% plant-available upon dissolution.
Always give 10% runoff or more. This avoids buildup in medium and makes any nutritional problem simply a matter of fixing your formula.
lots of myths around coco, like that it needs excess calcium. This is only true if it was poorly produced coco. If buffered poorly, it will leech Ca. If that ever happens, stop buying from that brand, lol. Make sure it's washed and buffered, or you have to do that at home. Better yet, use promix hp or bx... no concern about buffering and salt poisoning your plants with a bad batch. just add more perlite or similar as mentioned above.
