If you're watching your PH (and you should be), water your coco coir until about 20% runoff and test it.. Keep doing this until the run off comes out at the same PH it went in at, this works with coco coir and Not soil. Sometimes you get a good build up of salts from the nutes and the coir could use the flush if you don't water to runoff.
