honestly its your own preference your more prone to algae blooms during cycling so leaving your lights on wont help there, but youd need light if you were trying to save any corals. lights wont effect your cycle and it wont hurt to run them a few hours a day either.
some say running actinics 24/7will help in coraline growth while your starting your tank for a couple weeks.
also remember anytime you add liverock thats been out of the water for any period of time to a tank your bound to see an amonia spike be it big or small
