- The old leaves take a greenish gray color and then change to a bronze or yellowish brown color and the edges of the leaves flutter.
- Plant growth is slow.
- There is a lack of homogeneity in the growth of one fruit.
- Light yellowing on the edges of the leaves followed by progress yellowing along the veins and the color of the edges to dark brown.
- Minimizes root growth where secondary erosion in roots and tubers decreases, resulting in thin, weak storage members (roots or tubers).
- On the other hand less storage capacity and clearly shows that potato plays an important role in the thickening of the tubercle shell and thus works to protect it from diseases, especially black crust disease.
- In tomatoes and potatoes, the leaves become coarse and curled, and their edges are turned down, yellowed and turned brown at the end.
- Also when potassium deficiency in the plant accumulates dissolved nitrogen and increase the incidence of diseases.
