For example, I have a lot of plants inside (African violet, geranium, coleus, etc.) and outside (dolichos, petunia, pansy, asters, etc.) my home. Also, I have a lot of chemicals (such as ammonium nitrate, magnesium sulfate, ammonium molybdate, etc.) that can be used to compounding or correction of fertilizers. But I found only individual science research for geranium or petunia (for example). Is there a directory of precise dosages of fertilizers for indoor/outdoor plants?
No, I'm afraid not. Because plants vary in their requirements in terms of fertilising, it's more usual to start with the plant you want to feed and check what it requires in case it's anything particular (orchids, for instance, have specialist feeds available). At a very simplistic level, feeding also differs depending on the results you want - for instance, you mention Coleus, which is usually grown for its decorative leaves and not for its flowers, which would mean a fertiliser with a higher N level than K is more appropriate, whereas a plant grown for its flowers might do flower better with a different formulation. I'm not sure how you'd source the full readout of NPK plus trace elements required for every plant, nor do I believe any such resource exists for all flora.
Because it's quite a complicated area, proprietary brands of different feeds are available, ready mixed, with or without trace elements, because unless you're a chemist as well as a horticulturalist, working out precisely which chemicals to mix for different plants would be extremely difficult. I imagine its possible you have some sort of chemistry background though, if you already have the chemicals you mention available.
