Atami ATA Calmag 5L 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 or demineralised water, it can also supplement a normal fertiliser 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 plays a central role in chlorophyll and the plant's ability to capture light energy.
Atami also formulates ATA Calmag with iron, providing a fast-acting mineral supplement that can help address three commonly important elements within one product.
ATA Calmag is particularly relevant in cultivation systems where the source water contains little calcium and magnesium. This includes reverse-osmosis water, rainwater, naturally soft water and other demineralised water sources.
It can be used with soil, coco and hydroponic cultivation and is compatible with Atami's mineral feeding programmes. The general application range is 0.1-1ml/L, allowing the dose to be adjusted according to water quality, crop requirements and the wider nutrient programme.
Why choose Atami ATA Calmag?
- Calcium, magnesium & iron supplement - supplies three important mineral elements in one concentrated additive.
- Helps prevent deficiencies - particularly useful where source water or the growing system provides insufficient calcium and magnesium.
- Supports stronger cell walls - calcium plays an essential structural role within developing plant tissue.
- Supports chlorophyll production - magnesium is a central component of chlorophyll.
- Supports photosynthesis - adequate magnesium helps plants efficiently capture and use light energy.
- Supports nutrient uptake - Atami positions ATA Calmag as a supplement for improved nutrient absorption and healthier crop development.
- Fast-acting mineral formulation - designed to provide readily available supplementary nutrition.
- Ideal for soft water - particularly useful where naturally low mineral content leaves calcium and magnesium levels inadequate.
- Excellent for RO water - helps rebuild calcium and magnesium levels removed during reverse-osmosis filtration.
- Suitable for rainwater - useful where captured rainwater forms the basis of the irrigation supply.
- Suitable for coco - especially relevant because calcium and magnesium management can be important in coco cultivation.
- Suitable for hydroponics - useful in mineral feeding programmes where source-water composition can be closely controlled.
- Suitable for soil - can supplement soil feeding where additional calcium and magnesium are required.
- Flexible 0.1-1ml/L dosage - allows supplementation to be matched to water quality and crop requirements.
- Commercial 5L format - suitable for larger reservoirs, nurseries and regular professional use.
Extra calcium for stronger plant structure
Calcium performs an important structural role within plants and is closely associated with the formation and stability of cell walls.
Rapidly developing plant tissue requires an adequate calcium supply, making consistent availability particularly important during periods of active growth.
Atami describes the additional calcium supplied by ATA Calmag as supporting stronger cell walls and greater plant resilience.
Calcium availability is influenced not only by the fertiliser programme but also by source water, substrate, irrigation strategy and environmental conditions. ATA Calmag allows growers to supplement calcium where the existing supply is insufficient.
Magnesium for chlorophyll & light energy
Magnesium performs a very different but equally important role. It sits at the centre of the chlorophyll molecule and is therefore directly associated with the plant's ability to absorb light energy.
An inadequate magnesium supply can interfere with normal chlorophyll function and photosynthetic performance.
ATA Calmag provides additional magnesium alongside calcium, helping growers maintain adequate availability where the source water or normal nutrient programme does not provide enough.
Atami summarises the relationship simply: more magnesium supports more chlorophyll and energy, while calcium supports stronger cell structure.
Calcium & magnesium with added iron
ATA Calmag is not simply a two-element calcium and magnesium product. Atami's current formulation also includes iron.
Iron is an essential micronutrient involved in important plant processes associated with chlorophyll formation, enzyme activity and energy metabolism.
Combining calcium, magnesium and iron makes ATA Calmag particularly useful where growers want to strengthen the mineral profile of low-mineral irrigation water before or alongside their normal fertiliser programme.
Ideal for soft, RO, rain & demineralised water
ATA Calmag is especially useful when the irrigation water itself provides little calcium or magnesium.
Reverse-osmosis water has had the majority of its dissolved minerals removed. Rainwater can also contain very little calcium and magnesium, while naturally soft mains water may provide significantly lower levels than harder water supplies.
Atami specifically recommends ATA Calmag for soft and demineralised water, allowing growers to supplement these minerals before or as part of their normal nutrient programme.
This is particularly useful in professional cultivation where source-water composition is considered as part of the complete fertiliser strategy rather than treating every water source identically.
ATA Calmag for coco growing
Calcium and magnesium management deserves particular attention in coco cultivation because coco's cation exchange characteristics can influence the availability of calcium, magnesium and potassium within the root zone.
Properly prepared and buffered coco helps manage these interactions, but source-water mineral content and the chosen base nutrient still determine whether additional supplementation is required.
Atami identifies coco as one of the growing methods where ATA Calmag can be particularly useful, especially when combined with soft, rain or reverse-osmosis water.
Growers should consider the calcium and magnesium already supplied by their base nutrient before selecting the final ATA Calmag dose.
ATA Calmag for hydroponics
Hydroponic growing gives the grower direct control over the mineral composition of the nutrient solution, which makes source-water quality especially important.
If the starting water contains very little calcium and magnesium, the final nutrient solution must provide these minerals through the feeding programme.
ATA Calmag is fully compatible with Atami's mineral nutrient programmes and can be incorporated into hydroponic feeding where additional calcium, magnesium and iron are required.
Atami's current hydro grow guides use ATA Calmag throughout growth and flowering, with the precise concentration adjusted according to crop stage and the overall programme.
How to use Atami ATA Calmag
Atami's general dosage for ATA Calmag is 0.1-1ml per litre of water.
Use ATA Calmag to enrich water that is naturally poor in calcium and magnesium or as a supplement to the normal fertiliser solution. Atami recommends using water at approximately room temperature, around 21°C, for optimal results.
At the full 0.1-1ml/L range, a 100L reservoir requires 10-100ml, a 500L reservoir requires 50-500ml and a 1,000L reservoir requires 100ml-1L.
The correct dose depends on the starting water, growing medium, base nutrient, crop stage, plant condition and whether supplementation is preventative or being used to address an identified shortage.
Atami's grow-guide rates are guidelines rather than fixed requirements. Monitor the crop and overall nutrient strength when adjusting supplementation.
Helping prevent calcium & magnesium deficiencies
ATA Calmag can be used proactively when growing conditions are known to provide limited calcium and magnesium, rather than waiting for visible deficiency symptoms to become established.
This is particularly relevant with reverse-osmosis water, rainwater, soft water, coco and hydroponic systems.
Atami also highlights intensive LED cultivation as a situation where calcium and magnesium demand can deserve additional attention.
Visible plant symptoms can have several causes, however, including pH, root health, nutrient antagonism and environmental stress. Increasing Calmag concentration should therefore not automatically be treated as the solution to every apparent deficiency.
Designed to complement your base nutrient
ATA Calmag is a supplement rather than a complete base fertiliser.
It provides additional calcium, magnesium and iron where these elements are required, while the normal base nutrient continues to supply the broader macro and micronutrient profile needed by the crop.
ATA Calmag carries an N 6 W/W analysis, so it also contributes nitrogen to the final nutrient solution. This should be considered when building a complete feeding programme, particularly during later crop stages.
Growers using several mineral additives should monitor total nutrient concentration rather than assessing each product in isolation.
Using ATA Calmag with Atami nutrients
ATA Calmag is designed to integrate with Atami's mineral feeding programmes and can be used alongside base nutrients for soil, coco and hydroponic cultivation.
Atami's current grow guides include ATA Calmag alongside nutrient programmes such as ATA soil feeding, B'cuzz Hydro A&B and other mineral base feeds.
The amount required varies between programmes because the base nutrient, substrate and crop stage already influence the calcium and magnesium available to the plant.
This is why ATA Calmag should be viewed as an adjustable mineral supplement rather than a product that must always be applied at its maximum concentration.
Do you need Calmag with hard 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 a high dose of Calmag without considering the starting water may therefore provide more mineral supplementation than the crop requires.
Growers should consider source-water analysis or EC, the base nutrient formulation, substrate and plant response before deciding how much ATA Calmag to use.
The broad 0.1-1ml/L application range gives growers flexibility to match supplementation to their actual conditions.
5L Calmag for commercial & high-volume growing
The 5L format is ideal for commercial horticulture, larger reservoirs and growers regularly using low-mineral water.
At the maximum 1ml/L rate, one 5L container can prepare approximately 5,000 litres of supplemented irrigation water.
At 0.5ml/L it can treat approximately 10,000 litres, while at the minimum 0.1ml/L rate it can treat up to approximately 50,000 litres.
This broad treatment range reflects the fact that ATA Calmag dosage should be adjusted according to water quality and crop requirements rather than applied at one fixed concentration in every situation.
