I would go to the LFS to get your PO4 tested AND to acquire some nitrogen and phosphorus fertilizers if they have them.
BTW, you know for sure from your own tests that you need a nitrogen supplement.
Here's some info you'll be able to use:
A Nitrate Dosing Calculator For Better Tank Health (And Better Coral Color!)
Get a complete picture by getting the PO4 tested before commencing a plan though!
