Symptoms of nitrogen, phosphorus and potassium deficiency in vegetables

1) The first leaf of the nitrogen deficiency fertilizer is light green and gradually yellow, and the plant will also have such changes. Changes in nitrogen deficiency usually begin with the old leaves, and slowly the entire vegetable will turn pale green or brown. 2) When the growing vegetable lacks phosphate fertilizer, it will show slow growth, small leaves, and green spots. The back edges of many vegetable leaves become reddish purple, and fibrous root growth is retarded, delayed and mature. 3) When the vegetables are deficient in potassium, they initially show symptoms on the old leaves. The base of the plants is grayish green and yellow-brown, showing spots along the veins. The roots of the plants are stunted, the stems are slender, hardened and rich in wood.
