Unfortunately anything organic is going to be unbalanced (for what you're looking for). A good soil needs nothing added to it, and fish emulsion should be treated as supplemental not substitutional. Get by on what you can now, do some topdressing. Then in the fall /winter work in as much damn compost/organic material/animal poo as you can find. You may find you don't even need any additional ferts.
