Does my dosing sound reasonable?

Hello fishianados!

I have a fairly new (6 weeks) 12 gallon long tank with a couple of Otos and a some hair grass. I intend to plant HG this weekend and get some tetras as the cycling seems complete.

According to my naive fumbling with various calculators, these are the ferts I should use:

(total weekly dry dose):
KNO3 = 555 mg;
K2SO4 = 759 mg;
KH2PSO4 =84 mg;
CSM+B = 347 mg;

I'm also dosing Excel according to bottle instructions and using a Finnex FugeRay Planted+ 36" sitting on top of the tank for lighting.

Do you think my dosage calculations are correct? Will i need CO2 with this lighting/ferts or will Excel be enough? Should I raise the light? Is a goal of 7.5 ppm NO3 sound too low?

Any feedback would be greatly appreciated as I'm new to all this. Thanks!

If you are dosing via the normal EI method, it would be that amount of each 3x per week.

That's what I thought! Then when I put those quantities into the Fertilator, its looks like the totals would put me in the right range, and 3x that would kill fish. What am I missing?
