It sounds like you have a pH issue in the soil. If it is not responding to fertilizer, then it could be way to high of a pH for it to be available to the plant. I would get a kit to test the pH, and adjust down with iron sulfate until it is between 6 and 7. If you get it too low, then you can buffer it back up with dolomitic lime.
