Re- pot during 1st week of flower

I don’t see why you’d kill it. You risk stressing it a bit but she should bounce back. Should be early enough to keep pushing through. A bigger pot would definitely help and fabric pots are awesome. I just transplanted two cloned today. One was in a plastic pot and the other in a fabric pot. The root ball of the fabric one was cool. No root bound as it air prunes itself. The plastic potted plant was in early stages of getting root bound. Anyway good luck with your grow bro.
