Microbes pre digestion

Hello guys what up? I have always wondered how hydroponics fertilizers differed from regular synthethic ones and how they were produced- I've often times wondered about predigested organic nutrients and how it would fare against synthethic - look at this page on FB and the predigestion from airborne microbes to break down the nutrients - could a fermented plant extract FPE not be used in a hydro system if broken down by LAB bacteria? https://m.facebook.com/GuardenersoftheLand/photos/a.795578457231007/996265333828984/?type=3
