"It's getting crowded in here" (Photos)

Have a look. Am I gonna have trouble flowering these in this space? It's about 32inches by 27 inches wide (and 6 feet tall). The main stalks are tied down right now but I'm about to take them off cause I don't want the girls to get any wider. I think I have more vertical room to work with than I do horizontal. Is that sound thinking?

I posted the photos a little backward but just look at the dates on them. They are growing out fast. I'm not complaining, but should I worry at all?

No worries, your thinking is sound.
