like he said I would wait till week 3-4 then prune all the lower branches that are too far below the majority of the bush to get adequate light. also I would prune out a lot of those larger fan leaves on the lower portion and tops to allow light to penetrate down into the canopy. if you prune all the plants good and shove em together like one big bush you will be fine. you could also leave em alone but everything below the middle portion most likely will just yellow off and be little popcorn buds. easier and better to just take some time and remove some fan leaves and branches to increase space for buds to grow in and airflow.flower soon and remove all the lower crap that wont get any light anyhow..concentrate on tops...yeehaw
