Coco coir is meant to be moist all the time!
If you take a bit of coco coir from the top of the pot and you squeeze it you should feel water between your fingers - this is the ideal. If you squeeze it and it drips a moderate amount of water let it dry a bit. If you start seeing the substrate dry on top or you lift the pot and it's light you should water immediately. Always water with nutes and always allow for runoff of 15-20% to volume you used to water that pot.
