Yes, the numbers look good except for K2SO4. Recalculate and look at the amount of potassium added through KNO3. You'll see that it provides 4.7ppm of K. The EI dose for K is 7.5ppm. What KNO3 provides is usually enough alone. However, if you want 7.5ppm you will only need to add about 2ppm not the full 7.5. So 5 grams of K2SO4 in 750 ml would be sufficient.

No worries! It won't make a bit of difference. That's one of the beauties of dosing non-limiting nutrients. As long as you're dosing "above the barrel" it's all good. You would have to dose an extreme amount of potassium to cause problems. You're not even close . It's simply not necessary.
