So it won't effect anything other then sexing your plants to figure out if it's male or female. Re-veging is normal when you find out the sex of the plant. The best thing I have learned is wait to 5 internodes (5 true leaves) then change your lights to 12/12 to sex or to flower. The lighting of 18/6 or 24/0 is for vegitative life cycle of the plant. But all in all no harm done.
