Tomato lack of potassium: leaf margin chlorotic chlorosis, but the yellowing is limited to the margin of the leaf, severe yellowing and curling old leaves fall off. The resulting fruit is poorly colored, and if it is deficient in potassium, it is also prone to green husks due to excess nitrogen. Prevention and control measures: During fruit harvesting period, spraying with 0.3-0.5% potassium sulfate or potassium dihydrogen phosphate can increase the fruit-picking period.
Tomato lack of calcium: the initial young leaves are small, burning-like, kaki-shaped and curly, easy to brown; later tip and leaf margin withered, growing point of necrosis, flowers easily fall off. Slow fruit development, uneven maturation, uneven coloration, but also the formation of rot fruit. Control measures: Spray with 0.3-0.5% calcium nitrate or calcium chloride solution.
Tomato lack of boron: leaves deformed, brittle and fragile, some leaves chlorosis, slow growth, severe growth point necrosis. Fading spots on the surface of the fruit, followed by depression, inconsistent maturity. Control measures: The result is sprayed with 0.1-0.2% borax solution.
