First 1 to 2.5 weeks of flower u will stretch so if you are already 1 I would say hold off to prevent possible damage. If you'd like a simple flat soil like box around or another larger square can be placed outside your pot.
Then either carefully remove bottom or drill holes. Before placing inside larger pot. This is still possible damage! And would still suggest not.
If anything pull the plant apart to allow greater light penetration or get rid of some fanners.
