Ammonium sulfate is your 21_0_0.
Stable nitrogen source and the sulfer is good in our alkaline soil.
The that last number in your mix , potash is seldom needed in central Texas unless your removing hay. 30_10_0 is the most popular mix far and away. A mix of urea and ammonium sulfate.
Goes without saying...soil test.
