Phosphorus. With this deficiency, the lower part of the leaves acquires a bluish color. In this situation, it is advisable to use superphosphate.
Potassium. In such cases, twisting the upper leaves and the appearance of a brown border on them are noted. To make up for the balance of this element, potassium sulfuric preparations are used.
Gland. Such a deficiency is discussed with the appearance of obvious signs of chlorosis in tomato bushes. The main fabric of the sheets turns pale, and on its background there are veins of a bright green shade. To eliminate the deficiency of this element, iron is used.
Calcium. If the tomatoes lack this particular substance, they will grow thin and excessively elongated. To saturate plants with this element, it is recommended to use calcium nitrate.
