I’m growing green crack. 5 weeks into flowering. Is it a must to be on a 12-12 cycle or can I add more light hours now that it’s fully established??
You need to stay with 12/12 if it is a photoperiod plant or the plant will reveg. It doesn’t matter if you have an auto.

I second @MidwestGuy if you increase your light hours your plant will reveg. You can go backwards but not forward during flower.
