Athena Cal Mag delivers a precise balance of calcium (Ca) and magnesium (Mg), essential for robust cell structure, efficient photosynthesis and strong plant development. For growers using soft or reverse-osmosis (RO) water, inert media such as coco coir or rockwool, or for preventing mineral deficiencies during growth, this supplement maintains plant vitality and yield potential.
With a clean, water-soluble formula that mixes seamlessly with your nutrient programme, Athena Cal Mag ensures straightforward feeding and consistent performance across houseplants, vegetables, herbs, and larger container or hydroponic crops.
Key Features & Benefits
- Prevents Calcium & Magnesium Deficiencies: Addresses weak stems, poor root development, leaf yellowing and blossom-end issues often caused by soft or mineral-depleted water
- Supports Strong Cell Structure & Nutrient Transport: Calcium strengthens cell walls and roots, while magnesium supports chlorophyll production and photosynthesis for healthier growth and richer foliage
- Ideal for RO Water, Soft Water and Inert Media: Ensures nutrients are available in coco, rockwool or hydro setups where water lacks minerals naturally
- Clean, Soluble & Easy to Mix: Dissolves instantly and blends well with base nutrients or boosters, without clogging drippers or irrigation systems
- Flexible Use Across Growth Stages: Can be used throughout vegetative and flowering phases, whenever additional Ca/Mg support is needed or as a preventative measure
How to Use / Application Guidelines
Shake well before useAdd to clean water before mixing base nutrients or other additives to ensure maximum solubility and prevent nutrient lock-out
Typical dosage: 2.5 mL per US gallon of water (or follow Athena’s feed schedule), adjusting for water quality, growth stage and plant needs
Monitor EC and pH after mixing, especially important in coco or hydro systems
Use throughout all growth stages, from early vegetative growth through flowering, particularly with RO water or inert media
Frequently Asked Questions (FAQ)
Why should I use Athena Cal Mag instead of just base nutrients?Base nutrient mixes may lack sufficient calcium and magnesium, especially with soft or RO water or inert media. Athena Cal Mag ensures these critical nutrients are available to prevent deficiency symptoms.
What problems does a calcium/magnesium deficiency cause?
Calcium deficiency can lead to weak cell walls, poor root and stem development, distorted new growth or blossom-end issues. Magnesium deficiency affects chlorophyll production and photosynthesis, causing yellowing leaves and reduced growth vigour.
Can I use Athena Cal Mag with hydro, coco or soil?
Yes. Athena Cal Mag works with hydroponic systems, coco coir, rockwool and traditional soil media.
When should I add Cal Mag to my feeding routine?
Add to water first, before other nutrients, then follow with your regular feed. Use during active growth or if Ca/Mg deficiencies are suspected, especially with soft or filtered water.
Will Athena Cal Mag interfere with my existing nutrient program?
No, when used as instructed. Monitor EC and pH after mixing and adjust as necessary. Follow a balanced feeding schedule and avoid overuse to prevent nutrient imbalance.
Athena Cal Mag ensures your plants receive the calcium and magnesium needed for strong roots, healthy foliage and robust yields, particularly when using RO or soft water, coco, or hydro systems. Its clean, soluble formula and flexible application make it an essential supplement for growers seeking consistency, quality and peace of mind.
By preventing deficiencies before they occur and supporting optimal nutrient uptake, Athena Cal Mag helps plants reach their full potential, resulting in greener growth, stronger stems and improved overall performance.
