I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
That corn is stressed for some reason. Most likely a lack of water since it is in a container, although it could also be a nutrient deficiency such as phosphorus or potassium. I would not try to transplant it at this point but in the future you should start it in the ground.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
