Try flipping the lights out for one full day, then run a 12/12 light schedule.

The timing is not an exact science they will all likely finish at different times and since they are autos light switching may have little effect. Matter of fact I know a couple growers that ran 18/6 all the way through the grow with autos  
Hope this helps

12/12 may actually jump start the flowering in a auto flower  
You can leave them ynder 18/6 entire grow if you want  
I actually put mine under 12-12 after two weeks under 18/6
