## Overview

VitaLink CalMag 1L is a premium calcium and magnesium plant additive enriched with dual chelated iron forms, designed to enhance nutrient uptake, strengthen cell structure, and boost photosynthesis.

## Description

Product Description Calcium and Magnesium additive with beneficial iron Calcium and magnesium supplement with added iron Essential additive for plants during prolonged vegetative growth or when deficiency is observed. 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.

### ⭐⭐⭐⭐⭐ Great

Great stuff this bottle goes a very long way will definitely order more when needed which won’t be for a while as I still have loads left

### ⭐⭐⭐⭐⭐ Excellent product ,probably the best product for my veg garden.
*by M***. on 27 August 2025*

Excellent product , easy to use and it does the job it is designed for at a good price.

### ⭐⭐⭐⭐⭐ Very effective product. A must have for tomato growers.
*by G***E on 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.
