I would think u r gonna stress them out & possible hermie them , just put it on 10/14 & leave it be, people say 10/14 makes the plant think winter is almost here hurry & ripen as fast as you can but that is B.S., u should flower at 12/12 & leave them be, less light equals a longer flowering period because the light is what is ripening the fruit but if you patient enough to wait I would say for an 8-10 week flowering plant put on 10/14 lighting after 8 weeks & it should have extra fat fruit & be ready between 10-12 weeks
