Actually, you see where the pre-flowers are? When you put it into flower all the nodes on that branch will grow what looks kinda like a branch OUT of that node. That branch will be a bud, NOT a branch. The preflowers you see will mostly just stay where they are and not change.

Here's a couple pics. first two are 20 days into flower, the next two are 32 days. the last was just now. You can see the old preflower on the branch node.
