Aloha,
I also love using coco coir. It has been quite a learning curve. My mistakes were not understanding how to prepare it , before use. All the experts say rinse before using. I didn't. I finally used a hydroponic flush to get rid of the extreme sodium inside the coco. With a huge rinse of plain water after that. The next problem is that coco coir has natural properties that can react with liquid nutrients and cause lockout. I have also doubled my Cal-Mag for tomatoes. Lettuce and others do better at normal doses. Coco with care can last for years. I will break down, but add in some clean chunky coir and your back in business. Good luck and Aloha
