The pH level of the growing medium determines how fast and what elements your plants can assimilate. When the level is too high or too low, some nutrients are blocked and will not be assimilated by your plants, leading to deficiencies, regardless of whether the element is present. For this reason, it is recommended to keep the acidity levels between 5.5 and 6.5. Depending on the growing medium and the phase the plants are in, you can further adjust these levels.
