The 20-year-old actress was arrested Friday morning in L.A. and taken to the Van Nuys jail. We're told Ronni was booked on one felony count of corporal injury to a spouse or cohabitant.

Law enforcement sources tell TMZ ... police got a call to a home for a domestic disturbance, and when they arrived, officers say a man on the scene had visible injuries including scratches.

Cops say there was a verbal argument between Hawk and her boyfriend and at some point ... it got physical. Due to his apparent injuries, officers determined she should be arrested.

Hawk -- who's also known for roles on the shows, "Legacies" and "On My Block" -- had bail set at $100k.
