I'm seeing that too, but the plant is fading hard. I'd cut it if the leaflet die-back is creeping into the buds, like any fully dead brown leaf matter that will be too "inside" the bud to trim out. If not then u can wait. Did you use a fade/finish product? Looks great, really. If it was a huge room of this, I'd be cutting it just to ensure no mold but you can keep a close eye on this single plant.
