Should I flip to 12 hours?

Was wondering if I’d get a good yield if I flip this early or should I wait a little longer.

Looks like it's going to be tight fit mabye

Looks good. I’d minimize the branching though. I see 3 plants in 3gal pots filled about 2/3 of the capacity. 3-4 main colas per plant. The side branching will conflict with the other plants in that small space, but it’s not impossible.

Edit: try to keep the tops at an even height between the plants. It will help your yield.

I agree with what they said.
