Pruning in flowering?

So I just switched my plants to 12/12 like 5 days ago and they're pretty bushy. Should I prune them? Posting pic

are you new ? if so I am going to tell you no . so you know what branches you will need to prune next time . this time will be a learning experience . later you second or 3 grow you will know what lower branches to cut off so on .

They could use some trimming... helps with air flow and light penetration..
clean up all the small stuff around the base..

move your light up to make them stretch.
