Could be your lighting, you ferting, CO2, or all.
It would help to know all of the details to your tank...Lighting, CO2 or no...etc. I'm leaning towards light and ferts. CO2 could be it, but I doubt it. That plant is a weed and needs very little, but since it is the red type, it may need better lighting and ferts for the colors to show.
