I have seen quite a few people who switch their lights to 13/11 for about a week early in flowering (they say it enhances taste) they also say they have no problems with herms so i wouldn't worry about a 1 day incident.

that 'taste' theory is bunk, but it doesn't hurt anything, experiment for yourself ... the slight difference in light schedule, should not be a concern, nature has cloudy days, rainy days, etc ... the only thing nature does not do, is brightly illuminate the plant during the night hours ... (that is where, the stress problems appear) ...
