Mag/Cal – Calcium & Magnesium Supplement for Stronger Cells and Greener Leaves
Gardeners tend to obsess over nitrogen, phosphorus and potassium, the three headline numbers on every bag. Meanwhile, calcium and magnesium do much of the actual structural work without ever getting top billing. Calcium builds the cell walls; magnesium sits at the very centre of every chlorophyll molecule. Run short of either and no amount of NPK will save the day. Intense Nutrients Mag/Cal supplies both in a highly soluble form that plants can take up quickly.
It corrects calcium and magnesium deficiencies, the yellowing between leaf veins, the rusty spotting, the dreaded blossom end rot on tomatoes and peppers, and supports the physiological and biochemical processes that lead to stronger, lusher plants and better harvests.
Who Needs It Most
- Rainwater and RO users: soft or filtered water contains almost no calcium or magnesium.
- Coco growers: coco coir locks up calcium and magnesium, so supplementing is essential.
- Tomato, chilli and pepper growers: blossom end rot is a calcium delivery problem.
- Houseplant collectors: fast-growing aroids, Calatheas and Ficus quickly show interveinal yellowing when magnesium runs low.
- Anyone growing under strong grow lights, where demand for both elements climbs.
Key Benefits
- Provides structural support to cell walls
- Activates many of the enzymes required for plant growth
- Contributes directly to photosynthesis
- Improves leaf growth, fruit quality and overall plant health
How to Use
Designed for use with soft, rain or reverse osmosis water. Soil/coco: 1–2ml per litre. Hydro: 1–2ml per litre. Add to your water before your base nutrients.
🌿 Rose's Pro-Tip: magnesium deficiency shows on the older, lower leaves first, because the plant robs them to feed new growth. If the bottom leaves are yellowing between green veins, that's your cue.
Sizes
250ml, 1 Litre, 5 Litres, 10 Litres and 25 Litres. Add a measuring syringe for accurate dosing.
