Contains nitrogen and iron in forms which can be easily assimilated by plants. VitaLink CalMag is a unique calcium and magnesium additive. It increases the availability of calcium – which has poor mobility within the plant – especially for areas of new growth or fruit formation. Calcium is macronutrient important for strong cell walls, root development, cell division and elongation, nitrogen assimilation, enzymatic and hormonal processes and photosynthesis. A calcium deficiency can cause blossom end rot. Magnesium is a macronutrient which is vital for plant growth and health. It acts as a building block for chlorophyll which is crucial for photosynthesis. Nitrogen is an essential macronutrient for growth and biomass production. It is vital for the formation of amino acids and chlorophyll. VitaLink CalMag contains two forms of chelated iron to maximise the availability of this micronutrient to your plants. Iron acts as an enzyme cofactor in plants and is also important for photosynthesis. An insufficient supply can limit plant growth. The combination of all these elements improves the overall performance of your plants, resulting in healthier growth and colour. Usage instructions: Use 1 ml/L alongside main nutrients. Use during prolonged vegetative growth or when deficiency is observed. Check EC levels when using VitaLink CalMag because it will affect the EC of your nutrient solution. If required, adjust the pH. Recommended pH range 5.8-6.5. Shake well before use. VitaLink’s range of additives are specially designed to give optimum results when used alongside VitaLink nutrients. Ideal for use in all systems and media. Available in 250 ml, 1 L and 5 L bottles. Directions Shake well before use. Add to nutrient solution at the recommended dosage. Ensure the pH of your nutrient solution is within the optimal range. Apply throughout the growth cycle, especially during periods of high nutrient demand or if deficiencies are observed.

I like how it contains a little bit of nitrogen, helps boost the plants and keep them deep green.I'm posting this review now because I ordered 'VitaLink Calmag' and received 'Essentials Calmag' with no mention of the VItalink name anywhere on the bottle. Both products have full content list, and it is clearly exactly the same product with a different name. ### ⭐⭐⭐⭐⭐ Very effective product. A must have for tomato growers. *by on Reviewed in the United Kingdom 23 June 2025* This is a great product and does what it says on the bottle. I ordered it after getting the beginning of some tomato blossom end problems. A single application not only cured this but improved the general health of the plants. I will be using it fortnightly from now on . When I bought it I thought it was a bit pricey but the small amount used per application means it should last well. ### ⭐⭐⭐⭐⭐ A must for coco coir *by on Reviewed in the United Kingdom 12 September 2023* You can get this on offer which is great, gardening products can cost so much. Easy to use at 1ml per litre of multiples thereof. Contains iron with some calmag solutions don't. A bonus. Can be bought cheaper if you buy five litres instead. Just shake the bottle and pour into measure. No mixing of two part nutrients here. Already got a second bottle in the guidelines in case of need. Worth the money, and it works! ## Frequently Bought Together - VitaLink CalMag 1L | Calcium & Magnesium Plant Additive with Beneficial Iron - Gardeners Corner Growth Technology pH Test Kit 250ml Up & Down Solution Vitalink pH Test - Canna Coco 1L A&B Bottles Set --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/49325135-vitalink-calmag-1l-calcium-and-magnesium-plant-additive-with-beneficial](https://www.desertcart.tn/products/49325135-vitalink-calmag-1l-calcium-and-magnesium-plant-additive-with-beneficial) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-27*
