No need to top anymore. They look good. Just keep training them out to the edge of the pot. From where you are now looks like they can grow a little more vertical and then tie them down again. Keep doing that until you hit the edge of the pot. Then let them get a little height on them. Then it will be time to flower them out.Should I top the upper branches two tops.The two bottom branches have two new nodes .The two top branches just have one node coming out.
