Just incase you don't know, you need to have defeated the monster in Macelania before you can find any spheres (the elemental changing blob thing).

As I remember that Jecht sphere is outside the Besaid Auroch's locker room. Just teleport down from the Airship, or find your way to the main reception, then head up the stairs to the right corridor.
