If you are beginner in hydroponics, here are the 3 best hydroponic nutrients for vegetables.
If we give the plant what it needs, when it needs it, in the right amount, the plant will probably be healthy and productive according to its genetics.
Chiefly, there are 16-17 hydroponic nutrients. The elements C, H and O represent approximately 90% of the dry weight of the plants. Likewise, the elements K, Mg, Zn, Mo are enzyme activators. P and Fe are responsible for energy transfer reactions. And so on.
Emphatically, there are no absolute recipes for hydroponic nutrients that guarantee effective growth. The truth is that each person must observe, test and adjust to achieve the right balance between composition and use, depending on the plant species.

How Often Should You Change the hydroponic nutrient solution?
The frequency for changing the hydroponic nutrient solution is based on the number of plants and their size, volume of solution, among other factors. Generally, it is every 2-3 weeks.
Similarly, when there are drastic changes in pH. Also, it is important that you measure the pH and EC prior to changing the hydroponic solution.
Hydroponic Temperature Control
Overall, hydroponic plants have higher nutritional requirements in the colder months, therefore, it is essential that you analyze to increase, concisely, the amount of nutrient solution according to the type of plant.
Hydroponic nutrient deficiencies and excesses
A deficiency of a micronutrient is relatively easy to correct, but excesses or toxicities are very difficult to solve. For this reason, it is important not to introduce an excessive concentration into the hydroponic reservoir at the beginning or during the whole cultivation period.
Common symptoms of a nutrient deficiency and excess in plants
Nitrogen
- Deficiency: leaves are usually light green in color and old leaves are yellow-brown. Also, plant growth is slow.
- Excess: light green leaves.
Potassium
- Deficiency: leaf margins appear burned.
- Excess: yellow leaves.
Calcium
- Deficiency: brown root tips and leaves.
- Excess: yellow leaves.
Copper
- Deficiency: young leaves deform and die.
- Excess: slow growth and stunted roots.
