If it's only the lowest pair, don't worry too much. Old leaves naturally die off as they aren't making any sugars for the plant if they're in the dark. Usually they turn yellow first, but just make sure the rest of the plant looks healthy, that the dieoff doesn't spread up the plant before about week 6, and that your fertilizer schedule is good.
