What kind of fluorescent lighting did you use? The cool white and natural CF bulbs are supposed to be very close to natural light.

"My rhapis excelsa (fairly large at about 3' tall) was the only palm of mine that did not like artificial lighting last winter. It started looking bad after just a few weeks under fluorescent lighting"

It might not be a lighting factor. Quite often just being brought indoors is enough to shock the plant and have adverse reactions to indoor environments. Similarly, plants brought out in spring can react negatively.
