What are the minerals used in hydroponics?

In hydroponics, key minerals include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, which are essential for plant growth. Micronutrients such as iron, manganese, zinc, copper, molybdenum, and boron are also critical in smaller amounts. These minerals are typically provided through nutrient solutions tailored to the specific needs of the plants being grown. Proper balance and availability of these nutrients are crucial for optimal plant health and yield.
