The pH-value is crucial for cultivating plants. If it is too high, the creation of insoluble compounds are increased. It it is too low, the roots will be damaged.
(optimal pH-value: 5,8 - 6,2)
Measure the pH-value after you have added all componants of the fertilizer. If the value is too low, add Hesi PH+ to correct it. When you're doing this the first time you have to approach to the optimum slowly step by step (if necessary, drop-wise). Then note the final amount for possible later applications.
