If anyone can scientifically explain why a plant grown hydroponically would lack more flavor than one grown in living soil, then I'm all ears. Plants which are supplied the proper nutrients will grow according to their genetic makeup. They won't taste like oranges if you water them with orange juice and they won't be sweeter if you put honey in the dirt. All that stuff is hype. Plants need light, water and the molecular elements essential for photosynthesis. Their genetic makeup is what makes their terpene, volatile ester profiles unique. You can't alter that no matter what you feed them or how you feed them.
