Keep up with your current WC schedule and see if you can get your NO3 to near undetectable levels. I'd not worry about a quality test kit for now, but instead get a quality PO4 tester.
And ya, adding a Nitrogen source at this point is not recommended. I only brought it up as an option IF your levels started mimicking mine.
