I would recommend starting with a small dose of nutrients soon as coco coir doesn't provide a whole lot. Maybe 1/4 strength. Be sure to check and adjust the ph to where you want it. Shoot for 6-6.5 and this should help overtime bring you ph down a bit. I've never worked with the coco loco brand so I'm not sure how different from regular coco it is. With regular coco you can fertigate up to several times a day with run off and it won't cause root rot making it really easy to control the coco ph.
