Living beings such as plants require a proper balance, especially of nutrients, for optimal growth. Essential nutrients are necessary for basic functions, and trace nutrients for the best health.

Even if overdosing doesn't occur, nutrients can be wasted by adding too much solution per fertilizing cycle.
