assuming the coco is rinsed and buffered properly, "coco" nutes are the same as hydro nutes... it has to provide everything as there is nothing in coco.
Soil has nutes in it already... so, you want to slowly add more to your fertilization schedule as you go... so many variables make this impossible to give a simple answer. if it is hot soil, the nutes may last 2 months while a light mix might be depleted in a matter of a couple weeks. The differences in what is added is just another layer of variance. read the plant... react.. if you use the same soil product next time, you can adjust the rate you add nutes based on your experiences with the product.
do not worry about using these nutes in soil. it'll be the same concept as far as learning the balance of fertilizing soil. subsidize what is lost and maybe even needs full dose near end with some soil mixes -- a 1.5-ish EC (x/.5 calculation) range of feed. if you get to that point, treat it like a soilless grow. 10-15% runoff waste water. toss it outside, down drain, whatever. will maintain a consistent fertile soil.
the only difference is the fact it has amendments containing nutrients. if those get used up, it's essentially a soilless grow even though it's 'soil'. regardless, always make sure you have a good drainage component. if it is a heavy soil 50/50 with perlite or similar is a good idea. if it holds less water, you don't need as much.
