well you can't really return a plant at that stage into vegging again - so in the worst case you can lose a bit yield here as the last two weeks make up a good 25-35% of the total volume. likely the plant will stay in flower and it actually could increase the yield a bit as more light and therefore energy is provided to the plant.
i can't really try it as i have two strains in my flower room right now, so its all your still
