An algorithm designed to control the nutrient delivery rate in an automated aeroponics system executes fully without crashing or showing any compiler alerts. However, instead of increasing the nutrient delivery as the plants grow, the system keeps the delivery rate constant at the initial seedling level.
Identify the category of programming error that is responsible for this incorrect execution outcome.
