It can not possibly be a weight problem. You can fly with several gallons less fuel in one wing than the other and it is hardly noticeable. Once you have enough fuel imbalance to notice, the aileron trim takes it right out easily with very small adjustment.
The trim adjustment to fix a "heavy wing" is usually much greater. So it can not be from a physical weight difference.
What Carl said is right. The three biggest culprits are incompletely formed trailing edge bend, height of the aileron upper surface with respect to the wing upper surface, and warping/drooping of the fiberglass wingtip because it was attached with the ailerons out of rig.
