Aptus CaMg-Boost prevents Calcium & Magnesium deficiencies along with stimulating powerful fruit set and development.

Aptus CaMg-Boost is 100% soluble and when used at the correct dilution levels, helps improve the structure and firmness of flowers and fruit. Aptus CaMg-Boost provides the extra boost plants need during certain stages along with activating enzymatic activity to help raise the internal plant pH to aid the resistance of fungal attacks.


Use once a week from the third week until the fifth week of flowering. When adding CaMg Boost, do not use additional boosters with Phosphorus in it (PK 13/14, P-Boost, Super-PK, etc).
  • Use 5 ml per 10L of water.
  • Shake before use.
