With the objective to determine the probable causes of the appearance of abnormalities in BRS Topazio cotton plants, a greenhouse experiment was carried out per subtraction, in which nutrients were omitted: N, P, K, Ca, Mg and S, totalizing 21 experimental units. The omission of N, P, K and Ca in the nutrient solution reduced the biometric characteristics of the cotton crop, with K and Ca being the most affected by these characteristics. The visual symptoms in cotton plants are seen with more severity in the lack of K, P, K Ca and Mg elements. The omission of S did not affect the development of the plants.
