experience makes me think that perhaps you're at the end of the thread on the truss rod, and the 'forcing' you've felt is the nut trying to cut more thread on the rod..? Is it possible to take the truss rod nut off, insert a suitable thick washer, and try again..?

Spector's have a two-way truss rod and I don't think you can do this in the way you would with a traditional Fender style rod.
