With many corns, especially sweet corn, this is quite normal. Don't worry about it.

I'm sorry i estimated the height to be a little taller than it really is. It is more like 2 and half to three feet tall sorry

Back in the 70's on my produce farm, I had a variety of corn that had purple stalks and husks. Barely 4 ft and 2 good ears per stalk. Other varieties which mature early have the same results.

As an experiement for display as a novelty at the county fair, I planted corn in a seed starting tray. By the 20th of july it was 12 inches tall and tasseling. When it's time to produce corn will regardless of how tall it is.
