Question
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?

Answer
The plants which show symptoms due to the deficiency of more than one nutrient are grown in different sets in water culture. Set 1 is given one of the several nutrients showing deficiency symptoms, set 2 is given another nutrient and set 3 is given yet another nutrient. In this way, the different sets are grown in hydroponics by supplementing one of the different nutrients showing deficiency. The real deficient mineral element, if supplemented in the medium, causes plants to grow under normal conditions reverting the deficiency symptom.
