Well, it could be variegation, but I think it is more likely that you are dealing with a nutrient deficiency here. Make sure that you are feeding with a good fertilizer that contains miconutrients in addition to the normal N-P-K. Many ferts. such as triple 10 or triple 13 don't have any micros and this can cause the affect you are seeing. If you could gather a soil sample and send off to your local agricultural extension agency you can find out exactly what you are dealing with. I've seen my bananas do this many times only to have the grow out of it when I started doing a better job with fertilization.
