I wouldn’t, aside from trimming I try to touch as little as possible. Heavy sativas generally are “airy” and elongated by comparison with indica. Doesn’t mean you cant pull off dense sativa,you gotta really pound them with light. just don’t expect them to be like indica. Wait till after cure, they will stiffen up a bit.
What are your temps with the 60% humidity? If under 65° you probably have a couple days left.
