The fig tree (Ficus carica L.) is one of the oldest trees in the world, produces fruits with high nutritional content and is used for medicinal purposes. Currently, this crop has been especially important in Mexico, that is why this research was aimed at: analyzing the nutritional deficiencies induced in fig plants Ficus carica cv. Neza in hydroponic conditions using the missing element technique. To carry it out, six solutions were prepared, one with all the ions and five with a missing nutrient element. The experiment was carried out under a completely randomized design with six treatments (complete solution and five of them without a macronutrient: nitrogen, phosphorus, potassium, calcium and magnesium) with five replications. Growth variables were evaluated: number of leaves, height, stem diameter, number of fruits and leaf area. In addition, chemical tissue analyzes were performed to confirm nutritional deficiency and visual symptoms. Data were analyzed through ANVA and Tukey tests (α = 0.05). Significant differences were detected between the treatments without nitrogen and without calcium with respect to the complete solution (Solcomp) in the variables of growth and nutritional content, manifesting visually. In the treatment without phosphorus (SP) there were no significant differences. In conclusion, the information on the content of N, P, K, Ca and Mg in the leaf tissue will serve as a reference to producers of this species to correct nutritional deficiencies of these elements in the development of the fig tree.
