If a plant shows a symptom which could develop due to deficiency of more than one nutrient, how would you find out experimentally, the real deficient mineral element?

Solution: Plants that show signs of numerous nutrient deficiencies are grown in distinct water culture settings. Sets 1 through 3 are given three different nutrients and are grown in hydroponics with one of the nutrients showing deficiency supplemented. If a true deficient element is supplemented, the plant will grow properly and exhibit no signs of deficiency.
