Flowering and time

Wondering my girls are in flower about 2.5 weeks should I change lights 2 12-12 or stay with 18-6

Are your girls auto flower. I’m assuming they are if the flipped to flower. If so you can stay with the schedule you are running. If they are photos I would switch.

Sorry ya they autos

Yeah, I would just keep running 18-6. That’s what I do unless I got a photo mixed in the grow.
Hey ho lets grow

On Autos I would stay on a 18/6. I feel 12/12 hurts them aka low yield. At least from my experience as I grow only 12/12.

Thanks much

That’s the advantage of autoflowers you can supercharge your bud growth with 18-20 hours of light
