Maximise flowering density with Skyhigh Cal Mag Bloom. This nitrate-free supplement uses chelated Calcium and Magnesium with Boron and amino acids for bulk building, enhanced flavour, and stress resistance in hydroponic systems.
-
Drive maximum bulk building and flower density in your bloom phase with Skyhigh Cal Mag Bloom, the cutting-edge nitrate-free calcium and magnesium supplement. Designed specifically for high-performance indoor cultivation, this innovative flowering formula leverages plant-derived Calcium that is organically chelated for exceptional bioavailability. Enhanced with synergistic Boron to eliminate common nutrient deficiencies and a perfectly balanced Magnesium supply, Cal Mag Bloom maximises chlorophyll production for vibrant, healthy foliage. Ideal for all hydroponic systems, coco, and soil, this formula is your key to producing clean, ripe fruits with improved flavour and aroma.
Key Benefits of using Skyhigh Cal Mag Bloom
- Enhanced Nutrient Mobility: Enriched with synergistic Boron, which acts as a transport agent to ensure the essential Calcium (Ca) and Magnesium (Mg) move freely to the plant's points of greatest need, preventing deficiencies.
- Superior Bulk Building: A nitrate-free formulation incorporates vital amino acids to support rapid cell expansion and dense flower/fruit formation.
- Improved Flavour and Aroma: A unique blend of phenolic compounds and Sulphur stimulates secondary metabolite production, significantly enhancing the final quality, taste, and maturation of your harvest.
- Anti-Stress Protection: Contains anti-inflammatories and antioxidants that elevate your plant's resilience, protecting against environmental stressors like UV damage and heat stress.
- Maximum Bioavailability: Utilises expertly formulated, organically chelated, plant-derived Calcium to ensure maximum uptake, unlike standard mineral Cal-Mag products.
How to use Skyhigh Cal Mag Bloom
Skyhigh Cal Mag Bloom is highly concentrated and can be applied through regular watering or as a foliar spray.
Dosage
- Hydroponics & Media Feeding (Coco/Soil): Dilute 1–4ml per litre and apply with every watering or reservoir change throughout the entire bloom phase, up until your final flush.
- Foliar Application (Deficiency Correction/Boost): Use 10ml per litre for full leaf coverage. Apply under low light level conditions (e.g., just before lights out or during the dark cycle) to prevent leaf burn.
Pro-Tip: For optimal results in coco coir, consider using Skyhigh Coco Prime as your starting media.
Can be used on all grow mediums including coco, hydroponics and soil.
Available in 1 litre.
Frequently Asked Questions
Why is Cal Mag still needed during the flowering phase?
Calcium and Magnesium are crucial right through the bloom phase. Calcium strengthens cell walls, providing the structural integrity needed to support the weight of heavy fruits and flowers. Magnesium is central to the chlorophyll molecule, essential for photosynthesis, which provides the energy (ATP) needed for bud and fruit development. Deficiency during bloom can lead to soft, small, or poor-quality yields.Will using Cal Mag Bloom interfere with my base bloom nutrients or PK booster?
No, Skyhigh Cal Mag Bloom is formulated to be compatible with your base feed. However, Cal-Mag supplements can slightly raise your EC/PPM levels. Always add your Cal Mag first, and then your other nutrients (such as Skyhigh Alpha Roots or a PK booster) while monitoring your EC/PPM to ensure the total concentration remains within the optimal range for your plants.Can I use this product if I have hard water?
While hard water contains some Calcium, it often lacks a proper balance of Magnesium and other necessary elements. Skyhigh Cal Mag Bloom's high-quality, balanced formula (with added Sulphur and Boron) ensures your plant gets the ideal ratio of nutrients it needs, especially if you observe any signs of deficiency (like interveinal chlorosis, which is a common sign of Magnesium deficiency). For pure Reverse Osmosis (RO) water, Cal Mag supplementation is essential.Is it better to use Cal Mag as a foliar spray or mixed in with the water?
Mixing Skyhigh Cal Mag Bloom into your regular feed is the primary method for long-term health and deficiency prevention. However, applying it as a foliar spray (10ml/L) is highly effective for rapidly correcting visible deficiencies (like leaf spotting or yellowing) because the nutrients are absorbed immediately through the leaves, bypassing any temporary issues in the root zone or nutrient solution pH.What are the ingredients of Skyhigh Cal Mag Bloom?
Skyhigh Cal Mag Bloom is a highly specialised, nitrate-free formula. Its primary function is to deliver key secondary macronutrients and beneficial compounds during the flowering phase.The Guaranteed Analysis (NPK 0-0-0) and breakdown of key elements are:
- Total Nitrogen (N): 0%
- Calcium (Ca): 6%
- Magnesium (Mg): 3%
- Sulphur (S): 9%
- Iron (Fe): 0.3%
- Boron (B): 0.3%
