• Apply during cooler hours, preferably in the morning or evening, to avoid leaf burn and improve absorption.

• Adjust the NPK ratio to the specific deficiency:

- More N if lack of greenness and growth.

- More P if root development or flowering needs improvement.

- More K if the plant is weak, stressed, or the fruit is of poor quality.

• Keep the substrate slightly moist after applying granular fertilizers.

• Avoid applying to dry soil or during intense heat waves.

• Do not mix in the same tank with highly alkaline products or with calcium if using soluble NPK fertilizers, to avoid precipitation.

• Repeat every 2–4 weeks depending on the crop and formulation.

• Use moderate doses on young or sensitive plants, such as ornamentals, herbs, and houseplants.

• In poor or heavily leached soils, it may be necessary to combine NPK with organic matter to improve nutrient retention.
