I think it would be chanigng hte light cycle. i mean if you think about it, indoor growers are trying to mimic mother nature and only tweak it enough to make it better, not totally change shit. If you look at a plant throughout 24 hrs outdoors, it doesnt get even 18/6 so 24/0 was probably too much light. 18/6 doesnt even account for dawn, dusk and shady times of the day.
Im sure the nutes couldnt have hurt either
