This is part of a 4-part combo, made up of

• V-Basis (14-4-12) Nursery / Vegetative Fertiliser
• CA-Fortify (12-0-0) CalMag Additive
• K-Boost (1-0-31) Potassium Booster
• Absolute Flower (11-3-17) NPK Fertiliser

FORTIFY CALMAG FERTILISER IS USED FOR CULTIVARS THAT ARE ESPECIALLY PRONE TO CALCIUM DEFICIENCIES. IF YOU ARE FLOWERING A CALCIUM-HUNGRY CULTIVAR, OR IF YOU ARE GROWING IN COCO COIR OR PEAT MOSS, FORTIFY IS THE SOLUTION FOR YOU. 

Attention all coco growers! Designed for a 100-day release rate, this single-application, calcium/magnesium-fortifying solution is the plug-and-play product you have been searching for. Apply at a rate of 1.25 grams per litre of substrate.  

If you are using peat-free or coco substrate, Nitrogen draw-down can be an issue. The high N-content of CA-Fortify ensures Nitrogen remains available to your plants throughout. 

For best results, use in conjunction with Beanstalk Ag's Absolute Flower and K-Boost fertilisers.

Absolute Flower - 15- 20 grams per four litres of the substrate (minimum 3.75g per litre) 

K-Boost- 5 - 8 grams per four litres of the substrate (minimum 1.25g per litre) 

CA-Fortify- 5-8 grams per four litres of the substrate (minimum 1.25g per litre)
