Compost tea doesn't add any nutrients, it brings in beneficial bacteria into the soil so that they can break down the available nutrients for the plant to use.
As coco is an inert medium (doesn't have any nutrients), it will not bring any benefits for nutrient uptake. It could improve root health, not gonna do much for yield or potency though.
As a foliar, it can improve the plants resistancy to pathogens and disease. However I would not use it for this application alone either.
