With this nitric acid you will be able to adapt the nutrient solution to the most suitable pH for your substrate, this product must be handled with care because it can cause severe contact burns since it is nitric acid that will provide extra nitrogen to the solution. When using organic stimulators we must correct the pH since the acids eliminate very important characteristics of the stimulators.
When chemical fertilizers are used it is advisable to correct the pH after adding the fertilizers, the stimulators should be added with the pH corrected. B.A.C. pH down and pH up are also used to remove the bicarbonate from water with high hardness. To prepare the solution, pH down must be added until it reaches pH 5.2 and allow the acid to react with the bicarbonate, the water will then lower until pH 3, with pH up we raise the pH to the appropriate level according to the substrate that we use and if the fertilizer is organic or mineral, check pH in the tables.
