RbtAsq, I dont know where the hell your post went but the article is 100% about soil, Hydro is mentioned in 3 places and its in the word Hydrogen. The chemicals needed are all the same but I think they are absorbed differently in soil among a host of other things. Having the right Microorganisms at the roots and feeding them is a bit different too.  

If I get a cheap bag of soil from the local grocery store and a seed with good genetics I can have the Brix at 12% the whole grow no problem and very little Myco. With water grows like DWC, I have to work (and think) to get the brix up to 12% before harvest. I am getting there though.
