Your intonation seems to be out. That is an adjustment that is made at the bridge. Do NOT mess with your truss rod. Either take it to a professional and get it set up, or you can set it up yourself. UG has a set up tutorial thread with a section on intonation. It can be found HERE.

"damn close" is not close enough and there will be a slight sharp/flat difference the futher away you move from the intonation point, "ye can nee change the laws of physics" as scotty from star trek used to say.
