Paph Slavador Dali, Leaf Discoloration

[imacava]

This little guy seems to be going gangbusters, but the leaf that's getting generally lighter in the second photo, and the light spots on the leaf in the third have me wondering if I'm not getting into trouble. It has been living in an east facing window and I hadn't noticed a problem, but then it got somewhere in the neighborhood of four hours of light from some sort of anti-seasonal affectation disorder lamp that my roomate has (6 small but very bright fluorescent bulbs) when I was trying to do some intensive care for another plant. I'm pretty sure the yellowing leaf is a part of the normal life cycle, but am suspicious that those light spots could be a problem (I realize my accounting of the circumstances is far from scientific, but do those light spots look like characteristic light damage?).

Thanks,
Seth
