I would quit cuttin with perlite at all, it will have a tendecy to load up on the moisture and nutes which is counter to one of the primary benefits of coco. The air to water ratio and drainage are THE benefit so when you add perlite with the entent to retain more moisture in the media you just countered two of the main benefits. I would mix the Cocogro bales with a bale of large chips from Empire Organics and run it at 100% coco. no ph issues at all and easy cheezy on the maintanence.
