Theres your problem. Hydro. Ha
When things go wrong, they go wrong quickly. No soil biology to buffer the system. You have to KNOW exactly what youre doing. Dont get me wrong, I love hydro for indoor novelty growing, but its likely to throw wild swings in ph, ppm, etc if youre not on top of it. Have a good ph/ppm meter, know your nutes, and use RO water if you want to be sure.
Now Im not saying a hydro plant couldnt win this competition either, it would just have to have a res the size of a 55gallon barrel with the best aeration youve ever seen. Hell just grow into a continuous 55 gallon batch of AACT! That would be how I did it.
Even then, Id still put flavors of the fruits fed by soil up against hydro any day.
