Description
CANNA CalMag Agent is a concentrated calcium + magnesium supplement made for growers using soft water or RO water where the starting mineral level is low. By adding a clean dose of Ca and Mg back into your base water, it helps create a more stable foundation for your nutrient mix and can raise the starting EC to a more workable level.
Calcium and magnesium are essential for strong structure and healthy growth. When they’re missing, plants can struggle to feed consistently—especially under strong lighting, fast growth, or heavy flowering. CalMag Agent is designed to help reduce those common issues and keep your feed more balanced from the start.
Why growers use it
-
Helps prevent Ca/Mg-related deficiencies when using soft/RO water

-
Encourages stronger, healthier growth and improved flower development
-
Highly concentrated and easy to add to your routine

Raises the baseline EC of your water, often meaning your base nutrients can do their job more efficiently
Tip: Add CalMag Agent to your water first, then mix your base nutrients and additives, and always check your EC/PPM after mixing.
