She's a good, strong looking plant but the nodes are pretty close to each other and I would wait until you get a little bit of a stretch from her... You could move your light up a couple, three inches to encourage that but when she goes into flower, that will start to happen naturally. For now, I'd just be tucking the large fan leaves under to expose bud sites - they may not STAY under but you can keep doing it... When she starts to stretch, you can do something simple like cutting some strips of a soft piece of cloth, loop it around the branch you want to train to grow away from the main stem and pin it to the side of your pot (it LOOKS like you're growing in fabric?) ... if the branches are pliable enough, you should be able to get them to point 90-degrees away from the main stem... it'll look terrible at first - LOL! - but after an hour or two, you'll see the end of those branches start growing back up straight toward the light..
The other thing you can consider a little bit in the future is some defoliation as she gets into flower. Those are some huge fan leaves and I think this would be a great plant to do that on... but it must be done cautiously and wisely. This article has become my "bible" as far as defoliation is concerned - it gives you the how, the when and the why and is definitely worth the read even if you decide you don't want to go this route: https://www.growweedeasy.com/nebulas-super-simple-3-step-defoliation-tutorial
Good luck - you've got a magnificent grow in the works!
