Your 10 PM - 10 AM schedule seems off. The plants will only get 9 hours of sunlight (10 AM until 7:03 PM). Maybe try 7 PM - 7 AM?
Yeah you right, but I was hoping that the extra hours of darkness will do no harm. I was assuming minimum of 12 hours of darkness is required. I topped them earlier so will have to give at least 2 more weeks before flowering.
