Photo in auto tent

I have one photo in my autos tent and the autos already flowered

Should i flip my photo to 12.12 but i hear its not good for autos any suggestions

I have a balcony btw but not to good temps

I've done a few autos. seedling to about 10 - 14 days I keep lights on 24 /7. you want to give them all the help they can get in early growth. after 4 weeks growth is already slowing down and it's bud development time. so first two wks 24/7 after that I do a 20/4 till the end.
