I had a soil test on my yard which has St Augustine grass growing on it and it said everything was good except i had low nitrogen levels, what should i apply to raise the level.

Be sure you find the word organic on the label. Many, if not all, Medina products do not carry that word.
Every soil test shows low nitrogen. In an organic soil, they should be testing for protein. Protein is made up of amino acids which all have nitrogen molecules. The continual processing and reprocessing of amino acids by microbes is how organic soils get the nitrogen they need.
