If those containers do not let all extra water drain out freely, or the soil is not well draining, then yes. This looks to be an overwatering problem. Most commonly it will be Phytopthora or Verticillium. Sometimes they are treatable, but the best thing to do will be to discard soil, and sterilize the container. Start with fresh soil and fresh plants next season.
