What’s The Reasons For The Colors?

Deficiency in Nitrogen

The first and most prevalent cause is overwatering, which causes the cucumber plant’s leaves to become yellow, white, brown, or black. It is not a good sign when the cucumber plant leaves begin to yellow.

When too much water is immersed in the soil, it destroys the roots. Molds form on the sidewalls of the roots as a result of too much water, causing harm to the root system and stunting its growth. When the cucumber plant’s roots are injured, it stops taking up nutrients, resulting in chlorosis.

What Are Some Treatments

To solve this problem, make sure the plant is well watered. To solve the chlorosis problem, provide nitrogen fertilizer to the soil, which will appropriately dilute the soil and avoid root damage.

Nitrogen fertilizers are used to treat the plant, which is becoming yellow, brown, white, and black due to a nitrogen deficit.

Deficiency in potassium

Potassium shortage is another factor that causes the cucumber plant to turn yellow, white, brown, or black in color. When nitrogen deficit progresses to the inner sections of the roots, potassium insufficiency develops because the plant need more potassium to thrive at this level.

Potassium is essential for plant growth, and a lack of it causes the plant’s growth to be limited. A cucumber with a potassium shortage can develop a variety of ailments.

Treatment

Potassium fertilizer is provided to fix the potassium ratio that plants require. The cucumber plant will develop properly and swiftly once the potassium fertilizers have met the plant’s requirements.

The soluble potassium fertilizer is absorbed into the soil and reaches the root zone, where it corrects the potassium deficit.

Magnesium Deficiency is a condition in which there is a lack of magnesium in the

Another reason of cucumber plant discolouration is magnesium insufficiency (yellow, black, white. and brown). Excess potassium, calcium, and ammonium are the main causes of magnesium insufficiency.

When the leaves of a cucumber plant become yellow, it indicates that the plant is deficient in magnesium.

Treatment

Magnesium-rich minerals for the cucumber plant’s soil are required to alleviate magnesium insufficiency. You may also spray it on the soil to restore the greenness of the leaves and correct the magnesium shortage. Magnesium is required for photosynthesis and cucumber plant reproduction.
