I highly doubt it, but you've lost a few days growth.

The 36 hours of darkness isn't a herm-causing problem, but the 4 hours of light could have started the plant into flowering. Get it back on a regular light schedule and you should be just fine. Maybe think about how to prevent this kind of situation for the next time.

Happy growing, Frost! :thumbsup:
