The “Add Nutrient” light is controlled by a simple two-week timer that is designed to come on exactly two weeks after the "Reset" button is quickly pressed and released. . Whenever you press the "Reset" button, the AeroGarden thinks you are adding nutrients and will reset the “Add Nutrient” timing for another two weeks. If your “Add Nutrient” light is not coming on at two-week intervals and you are certain that no one has pressed the "Reset" button, the next step is to run the AeroGarden through a diagnostic procedure to make sure that the panel light itself is working. To run the diagnostic test, press and hold the "Select" button for several seconds and then release it. This will start a cycle during which the panel lights should all light up one by one in sequence, and the grow lights should go off and then back on. The Pump in the AG7s should also run briefly. If you discover that the "Add Nutrient" light does come on for a moment during this test, then the light itself is working and has been inadvertently reset.
To get the "Reset" button back in synch with when your nutrients are actually due, you will need to determine the calendar date when you last added nutrients. If you don't remember, look back to the planting date that you wrote on your Tending and Harvesting Guide when you planted your Seed Kit. and count forward in two-week increments from the initial planting date. When the next feeding is due, add the nutrients, fill the Bowl to the "Fill to Here" mark, and press the “Reset” button (even if it's not blinking). This will resynchronize your “Add Nutrient” light with the time that the nutrients are actually due.
