Dosing is just one facet of this, Light and CO2 are larger players.
Basically, EI was done for this experiment:


http://www.bio-web.dk/ole_pedersen/p..._2001_2_22.pdf

This way the nutrients are independent and they could focus on light and CO2.

EI does that, but that does not imply you just lard on ferts without any common sense, if you have a tank full of Anubias, or just 50% of the tank planted, you like do not NEED/REQUIRE full EI, you could like dose less, but dosing the full amount should also do no harm either. Still, no good reason on such tanks to keep dosing the full amount.

Most start high, then reduce down till they see a slight lull in growth, then return the last highest dosing rate.

You can modify the water changes and frequencies also and use the model calculator to see what the range of outcomes are.

For my 70 Gallon Buce tank, I dose the full EI, but.the tank is packed............
Likewise, the 120 Gallon is packed with fast growing stem plants, but if you have a tank with fewer plants, and mostly Anubias, ferns, a decent well fed fish load, or a sediment source of ferts as well, then you can get away with less water changes and less dosing of the ferts.

For new tanks, using CO2....... you should do 3x a week, 50% water changes for the 1st one to two months, till everything is well established first, before backing off the water changes. And tweak the CO2 well during that time frame.

Many do not, and then blame ferts, but CO2 is much more the issue, ferts are easy, you add them and then focus on other stuff.
