Many moons ago, there was a former chemical engineer in Florida that developed liquid fertilizers consisting of a single molecule that had the correct ratios of N, P, & K, with a variety a trace elements, to boot. I used one formula for about three years, but the business went kaput.

I find this absolutely fascinating. It has to be some organic long-chained molecule, I guess. And it might be able to dissociate in water? Maybe with the help of some other compound that will form a solution in water and then be able to act on the molecule? I share your regret that the business went kaput.

Tell us something about this MSU fertiliser that you mentioned earlier. Can one purchase this? Also why should semi-hydroponic be a term that has TM status?
