the node spacing is rather far apart, but not insane or anything. I would do what reaper said, just tie them down. You can slowly just bend the top 10-12" into 90 degree angles. The main cola on the end will turn back towards the light, and all those little bud sites along the top will now get a lot more light. Looks like its a little crowded so it might be a little challenge, but aside from cutting stuff down (definitely not what you want to do in flowering), thats your only option.
