Either cut it off (although that kind of thing always hurts the heart) or rotate it 45° to the right (or left) into the gap in the top two branches and let it grow. If they continued to grow like this, they would be shaded by the upper branches
Well have you topped the plant yet? I'd say let it grow to 5-6 nodes then top it to the 3rd node and remove all foliage below that 3rd node. Use some LST and mainlining. , and you should have a killer grow! Good luck!
