If you want to make a liquid solution from dry ferts for your 9 gallon tank you would need some dosing containers, 500ml bottles would be good for a tank your size. You would mix the following:

Bottle 1- MacroNutrients-
20.831 g KNO3
4.061 g K2HPO4
Fill to the 500ml mark with RO water, dose 10ml 3x per week

Bottle 2- MicroNutrients
13.043 g Plantex CSM+B
Fill to the 500ml mark with RO water, dose 10ml 3x per week on alternating days with the Macros.

Do a 50% water change on the 7th day.
