Light schedule

Well this is my first grow its an big devil auto fem 38 days old it has been under a 24/0 light, now that it's clearly flowering should i change the lighting schedule as i understood the thc production ocurs at night.
How is it looking?
What harvest can I expect and when can i expect it?
Thank you, waiting for your replies!

C'mon guys...

No ....its an auto ...it don't matter, but you might wanna go 18/6, if YOU FEEL thc is made at night ...lol

I agree with vostok it really doesnt matter if you change the ligt schedule. However My last auto I kept at 20/4 throughout. I just feel that the plants appreciate a small rest period.
