The nutrients you're using are organic, and while they will work in coco, they aren't ideal. They are going to take time to break down and become available to your plants, meanwhile you're expecting hydro results. I would either change your nutrients or chalk this run up to experience. Your girls are in flower, they appear to lack the proper nutrients and you don't seem to have the proper nutrients per se for what you're trying to do. It might make sense to finish out your grow for the sake of experience, but in the end, use it as a lesson, get the proper equipment and nutrients you need for growing in coco and try, try again.
