Fluval spec 3 Dosing schedule?

So I have a 2.5gal fluval spec 3 and I feel I'm on the border of figuring out a proper dosing routine. I have a high light and co2, I purchased the EI dosing jars from Green Leaf Aquariums. I've looked at some calculators and gotten my numbers here and there I just want to have a backup opinion. I'd love to make two solutions and dose those just a little confused maybe someone can help. I do have a scale I can measure with just no teaspoons currently.

Using this post


KNO3 23.1 gm (approximately 4 1/2 teaspoons)
KH2PO4 3.5 gm (approximately 3/4 teaspoons)
Plantex CSM+B 14.5 gm (approximately 3 1/4 teaspoons)
Optional: K2SO4 9.4 gm (approximately 1 1/2 teaspoons)

So from using this above I should take each mix with 500ml of water then dose roughly 2ml each 3x week to reach my tanks needs? Im assuming a half gallon of my tank is alteast taken up by substrate and rock.
Would it change anything if I mixed KNO3, KH2PO4 and K2SO4 in the same 500ml?
Keeping the plantex separate in its own 500ml
