Transplanting after flower

No, there’s no point now in doing anything. Those are several weeks into flower now. If it was beginning of flower I might say go for it. At this point, absolutely not. It’ll probably result in worse outcome than just leaving it

The risk of transplanting would be, if done incorrectly, it could stress the plant when it is not growing vegetatively and has less ability to bounce back. If it is still growing new leaves and stretching upwards in height it has the potential to form new roots as well, so a larger pot could potentially allow it to yield a little more. Its your call which way to go, but those are the most important factors at play! Happy growing 🌱👍

Yea, I would transplant right away. I wouldn't disturb the root ball though. To minimize transplant shock I would just plop the plant in the new pot without breaking up the root ball. Then the roots will eventually find their own way out. For the first week you'll have to water frequently and on the root ball until it grows roots out into the new soil.
