well heres my 2 cents... put them back on their orginal light schedule and quit over thinking it like they need to make up lost daylight... the more you mess with the light schedule the more issues youll have, hermying is the first thing that comes to mind. just leave them be and let them do their thing. just remember, keep it simple... they are plants, and sometimes things happen indoors and outdoors, like really rainy weather for a few days streight with lots of cloud cover its like dusk/dawn/night for the plants they dont get alot of light and slow down a bit but they always bounce back no problem, not just MJ just all plants. just dont mess with the light schedule too much, put them back on track as before and make sure your not tripping breakers again to avoid another possible interruption to the light schedule. its all good man dont fret.
