Canna pH (-) minus Bloom 59% H3PO4- it is a balanced mixture of acids with organic buffers that allow stabilization of the solution, supports the control of calcium in hard water.
The right level of pH in the nutrient solution is very important. Too high pH is the cause of the formation of insoluble substances, too low pH is dangerous for the root environment. It is also used to clean and disinfect hydroponic and irrigation systems as a cleaner removes salt deposits and impurities. The optimal level for most plants is: pH 5.8 to 6.2.
After adding all fertilizers, check the pH level in the tank. If the pH level is too high, it should be corrected with pH-, it is enough to add it very little(a few drops).
