Mike,
Let's put the shift lever in reverse and back up for a second shall we? After a careful read of your Subject title and of the data in your OP, it appears that this is a non injected tank. This makes all the difference in the world because CO2 grows plants. If this is the case then you absolutely have no need whatsoever to dose at the levels suggested for the previous EI links, which are targeted for high light, CO2 enriched tanks. Tanks such as those require high nutrient levels due to the high growth rate demands. Your tank will have 5X to 10X less growth rate, therefore you should probably throttle back your dosing significantly.
If you will keep a low tech, non-CO2 enriched tank, you only need to add nutrients four times or even stretch to twice a month. Also, assuming the tank will be heavily planted, there is no need to do any water changes. That's right - no water changes. As long as the lighting is not ridiculous and that you have sufficient plant mass the plants will recycle the organic waste from food and fish waste. As a result you can dose the following:
Instead of trace mix, consider something like Seachems Equilibrium add about 1/4 teaspoon per 20 USG of tank volume once every week or every two weeks.
Add about 1/8th teaspoon of KNO3 per 20G of tank volume once a week or once every two weeks.
Add about 1/16th teaspoon of KH2PO4 per 20G of tank volume once a week or once every two weeks.
Cheers,
