This problem has been plaguing me for years, and it finally dawned on me the other day how to fix these pretty easily. The issue is that when you're working under fluorescent lighting fixtures using iron ballasts, shooting about a certain shutterspeed (around 1/120th) can result in seeing a color and exposure shift in the image since the shutter is opening/closing midway through the fluorescent lamps cycle. Typically what happens is that after you WB the image you're either left with a cyan or magenta shift part way through the image. My solution to this is to use Lightroom's graduated filter tool to put in a cyan filter.
For the image below, what I did was drag a filter about halfway through the image (starting from the bottom, dragging to the top) click on the "color" section and then dialing in H:160 degrees, S:15%. From there I increased the exposure by .31. Looks much better, I think.
