Bionova pH-  is a 24.5% phosphoric acid solution. It is crucial to check the pH value of the water / nutrient solution with which we feed the plants. In fact, these absorb nutrients in the right quantities only when they are administered at the right pH value. If it is too high or too low, the plants will not absorb all the nutrients they need.
