Worth transplanting at flip ?

I got these two lit farms plants in 1 gallon plastic pots. Just flipped to 12/12 and was debating on whether to transplant to a 3 gallon or not. It's in coco/perlite. Can I get by with the 1's ? Would be my yields increase with a bigger pot ? This would be my first time flowering in 1's.

Transplant. Everything will be easier, and yields will be better

Be really hard to keep them watered I would go bigger

You could do it in 1 gallons but you would need an automated watering system and almost treat it more like hydro. You should have transplanted before flipping. I would transplant
