It's not really a "weight" capacity problem, but a physical capacity. It only has 4 pylons, and each rack can hold 2 munitions. If they added more pylons i don't think the wings have the structural integrity to hold any more munitions.

the inner pylons can carry 1500lbs each, and the external pylons can carry about 200lbs each (i.e. 2x100lb hellfires)
