Unit price perEstimated delivery between November 01 and November 03.
Atami ATA Calmag 1L is a professional, fast-acting calcium, magnesium and iron supplement designed to enrich water that is naturally low in these essential minerals. Particularly useful with soft, reverse-osmosis, rain and demineralised water, it can also supplement a normal mineral feeding programme where additional calcium and magnesium are required.
Calcium and magnesium are secondary plant nutrients, but both perform essential functions. Calcium contributes to the formation and strength of plant cell walls, while magnesium is central to chlorophyll and the plant's ability to absorb light energy.
ATA Calmag also contains iron, providing a convenient mineral supplement that can support calcium, magnesium and iron availability within one product.
It is particularly useful where irrigation water contains relatively little mineral content, including reverse-osmosis water, rainwater and naturally soft water. Calcium and magnesium management can also deserve particular attention in coco and hydroponic cultivation.
ATA Calmag is suitable for soil, coco and hydroponic growing and can be incorporated into Atami mineral feeding programmes. The general dosage is 0.1-1ml/L, allowing supplementation to be adjusted according to water quality, crop requirements and the wider nutrient programme.

Extra calcium for stronger plant structure
Calcium performs an important structural role within plants and contributes to the formation and stability of cell walls.
Rapidly developing plant tissue requires a reliable calcium supply, making availability particularly important during periods of active crop development.
Additional calcium can help maintain healthy structural development where the existing nutrient programme or source water does not provide sufficient quantities.
Calcium availability is influenced by more than fertiliser concentration. Source-water composition, substrate, irrigation strategy, root health and environmental conditions can all affect how effectively plants receive and use calcium.
Magnesium for chlorophyll & plant energy
Magnesium is located at the centre of the chlorophyll molecule and is therefore directly associated with the plant's ability to capture light energy.
An inadequate magnesium supply can interfere with normal chlorophyll function and plant development.
ATA Calmag supplies additional magnesium alongside calcium, helping growers maintain adequate availability where the source water or normal feeding programme does not provide enough.
This makes magnesium management particularly important for actively growing crops where healthy green foliage and efficient photosynthetic activity are required.
Calcium & magnesium with added iron
ATA Calmag is more than a basic calcium and magnesium supplement. Its formulation also includes iron.
Iron is an essential micronutrient involved in important plant processes associated with chlorophyll formation, enzyme activity and normal plant metabolism.
Combining calcium, magnesium and iron makes ATA Calmag particularly useful where growers want to strengthen the mineral profile of low-mineral irrigation water without unnecessarily complicating the feeding programme.
Ideal for soft, RO, rain & demineralised water
ATA Calmag is especially useful when the irrigation source naturally provides little calcium or magnesium.
Reverse-osmosis water has most dissolved minerals removed during filtration. Rainwater can also contain very low levels of calcium and magnesium, while naturally soft mains water may provide substantially less than harder water supplies.
ATA Calmag allows growers to supplement these important elements and account for the starting mineral profile of their irrigation water.
This is particularly useful in professional cultivation where water quality forms part of the complete crop nutrition strategy.
ATA Calmag for coco growing
Calcium and magnesium management can be particularly important in coco because the medium's cation exchange characteristics influence the behaviour of calcium, magnesium and potassium within the root zone.
Properly washed and buffered coco helps manage these interactions, but source-water mineral content and the chosen base nutrient still determine whether additional supplementation is required.
ATA Calmag is particularly useful in coco when the crop is being irrigated with soft, rain or reverse-osmosis water.
Growers should consider the calcium and magnesium already supplied by their coco base nutrient before deciding how much additional Calmag is appropriate.
ATA Calmag for hydroponics
Hydroponic cultivation gives the grower direct control over the mineral composition of the nutrient solution, making the quality of the starting water particularly important.
Where the source water contains very little calcium and magnesium, these elements need to be supplied through the nutrient programme.
ATA Calmag can be incorporated into hydroponic mineral feeding where additional calcium, magnesium and iron are required.
Final supplementation should be adjusted according to the base nutrient, source water, crop stage and overall EC of the prepared nutrient solution.
How to use Atami ATA Calmag
Atami's general dosage for ATA Calmag is 0.1-1ml per litre of water.
Use it to enrich water that is poor in calcium and magnesium or as an addition to the normal fertiliser solution where additional supplementation is required.
At 0.1-1ml/L, use 1-10ml for 10L, 5-50ml for 50L, 10-100ml for 100L, 50-500ml for 500L and 100ml-1L for 1,000L of water.
The appropriate concentration depends on source-water mineral content, growing medium, base nutrient, crop stage and plant condition.
Feeding programmes should be treated as guidelines and adjusted according to crop response, water analysis and local growing conditions.
Helping prevent calcium & magnesium deficiencies
ATA Calmag can be used proactively where growing conditions are known to provide limited calcium and magnesium rather than waiting for deficiency symptoms to become established.
This is particularly relevant with reverse-osmosis water, rainwater, soft water, coco and hydroponic systems.
It can also be used where crop condition and feeding analysis indicate that calcium or magnesium availability is inadequate.
Visible deficiency symptoms can have several possible causes, however, including unsuitable pH, root-zone problems, nutrient antagonism and environmental stress. Increasing Calmag concentration should not automatically be treated as the solution to every apparent deficiency.
Calmag support for intensive LED growing
Fast-growing crops under intensive lighting can place substantial demand on the overall nutrient programme.
Calcium and magnesium availability should be considered alongside the crop's other macro and micronutrient requirements, particularly where low-mineral water forms the basis of the nutrient solution.
ATA Calmag provides an adjustable supplement that can be incorporated according to crop demand without requiring the grower to replace the normal base nutrient.
Designed to complement your base nutrient
ATA Calmag is a supplement rather than a complete base fertiliser.
It supplies additional calcium, magnesium and iron where required, while the normal base nutrient continues to provide the wider macro and micronutrient profile needed by the crop.
ATA Calmag also contributes nitrogen to the nutrient solution, so this should be considered when building a complete mineral feeding programme.
Growers using several mineral additives should monitor total nutrient concentration and crop response rather than assessing each product in isolation.
Do you need Calmag with hard tap water?
Not every irrigation source requires the same level of calcium and magnesium supplementation.
Hard mains water can already contain significant quantities of calcium and magnesium. Adding the maximum Calmag concentration without considering the starting water may therefore provide more supplementation than the crop requires.
Source-water composition, base nutrient, growing medium and plant response should all be considered when selecting the appropriate dose.
The broad 0.1-1ml/L application range gives growers flexibility to match supplementation to their actual conditions.
1L Calmag supplement for regular growing
The 1L format offers a useful balance between treatment capacity and pack size, making it suitable for hobby growers, larger home growing systems and professional cultivation.
At the maximum 1ml/L rate, one 1L bottle can supplement approximately 1,000 litres of water.
At 0.5ml/L it can treat approximately 2,000 litres, while at the minimum 0.1ml/L rate it can treat up to approximately 10,000 litres.
For trade and wholesale ordering, ATA Calmag 1L is supplied in outer cases of 12 bottles, giving 12L of product per full case.
