If they're all autos you'll get the best yield if you switch to a 20/4 cycle. A lot of growers use the 24/0 balls to the wall method with auto's, but I personally feel that every living thing needs some down time too. With Autos I've tried 18/6 until flower then 12/12, ...24/0 start to finish, and 20/4 start to finish and get the best yield with the least problems with 20/4 every time. Hope that helps and best of luck!!
