What strain is that... GG4?
The plant looks fine. I would prune the smaller stunted leaves and branches at the center of the plant, if only to improve airflow and reduce the diversion of energy towards growing branches that aren't going to grow a lot of bud or will be shaded by the canopy.
In photograph 1, I would just prune the tiny leaves near the stem. All those leaves touching the medium are basically pathways for any insects on the top of the medium. And they block airflow. A lot of insects have a life cycle that takes them from the leaf, to dropping to the ground, to crawling back up the plant.
Witches Broom.
New strain in room. And the plant doesn’t look like it’s trying to shape into a witch’s broom tho. It’s actually just trying to grow horizontally. So I’m getting confused. Those pictures are maybe just the extreme cases which makes it harder to determine. What about the plant structure tells you it may be that? It’s only the bottom couple branches that are super weak. The others hold themselves up bottoms not so much.It is spelled Witch's Broom. I had it spelled plural instead of possessive. It is caused by several things. Around here broad mites, fusarium and nematodes were suspects and other things. Have you grown these before. There all wimpy, weak stemmed phenos of some strains.

Could just be hormonal disarray caused by an awkward topping on a weak and overly bushy plant.
Trim off the lower weak growth, especially the inner 2-4 nodes on every branch and elevate the highest branch tip into a vertical orientation above all the others.
If that is the problem the plant can recover in a weeks time, although it may require some additional pruning to maintain control.
Hi saw your post on the hops latent viroid thread. This is 100 percent hplvd in my opinion. Send out samples to a lab to be sure. Do not flower unless you are ok with sub par results.
