First time using Coco (Canna Prof), since seedling...

hey there Hazey bobby, you're right about the symptoms but i can tell you already know it's not that simple... dont worry , very simple to fix. So in coco you need nutrients, micro nutrients, and because the medium is sterile, you need something to break down the nutrients and micro for the plant which normally in soil would be done by bacterial life. So you need what's called a chelation agent, for example : enzymes, humic acid, beneficial bacteria, or even diluted H202 0.3% max. add that to every watering and you'll see your plant perk up almost instantly. Hope this helps ! 🚀
