what I do, is I tie, the giant fan leaf's, down to the center stem.. twist them side ways.

I remove fan leaves that are about to die off, yours look still very young.
I also prune sometimes, depending on how bushy the plant is, I usually leave the upper most top leaves & selectively prune the mid section, while tucking/twisting the top top leafs back to the stem
some strains like to be pruned lightly usually bushy plants that get pruned just love it.

I wouldn't worry about pruning or non pruning its a myth, just read your plant and do what you think it would like.
research some pruning techniques will help
