Should I transplant at the beginning of flowering?

It will definitely stress them but some stress is good! If you have a big 5 gallon bucket or whatever you want big enough you should be able to handle them carefully and just plant the whole chunk of root ball and dirt in a perfect size hole in the final container! It may mean you may want to run them a week or so longer because it may stunt growth for a little while but not over a week if done properly! Maybe sprinkle Great White in your final hole to help roots hook up! ?? Just MHO!

Do not transplant in flowering. If they get stressed during it you will regret it. Best to let them go now.

I wouldn't, already flowering being the reason. You're plant is now focusing on making buds, anything at this early flower stage could cause it to hermie, and repotting is the most stress we can cause. They all look healthy on that pic tho pal, be happy with how they are at the min and use this as a learning curve. I never repot, I always go straight into the big 4 gal pot from seed. Bigger pot, bigger roots, bigger plants.

Is bad idea to transplant plants during the flowering stage because their energy is focused on growing buds so if you damage their roots u will end up with a smaller harvest.. In flowering plant cant recover from damage like in veg that why you will end up with smaller harvest
