What are some signs of nutrient deficiencies in plants?

Symptoms caused by nutrient deficiencies are generally grouped into five categories: 1) stunted growth, 2) chlorosis, 3) interveinal chlorosis, 4) purplish-red coloring and 5) necrosis. Stunting is a common symptom for many deficient nutrients due to their varied roles in the plant.
