So what I do is that for a while to get those lower nodes started growing tall, when they catch up to mainstem I really it and start thing those branches down, this makes for a wide base that will be a ring of branches that get light and then let the thing go, as leaves fill into the center I'll thin em out as well as nodes that will never produce to focus on producing branches only. Plus I like a top cola or 4.
It won't grow quite as tall this way but will be a dome of even sized buds for most part.
