Macronutrients are essential elements that plants require in relatively large quantities. Some of these, such as oxygen, carbon and hydrogen, come from the air and water. Other macronutrients that all plants need are calcium, nitrogen, magnesium, potassium, sulfur and phosphorus. If your hydroponic garden lacks any of these elements your plants will fail to thrive and may appear stunted, with discolored and drooping leaves. You may be able to tell what's lacking by the symptoms; a plant that isn't getting enough nitrogen, for example, will be small and pale green.
