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.
- 50% Caliumhydroxid (corrosive!)
