Beschreibung
Ionic Cal-Mag Pro is a concentrated calcium and magnesium supplement designed to prevent and correct one of the most common problems in fast-growing plants: Cal-Mag deficiency.
When plants are growing hard, especially during heavy flowering, they can burn through calcium and magnesium quickly. If they run short, growth can slow down, leaves can pale, yellowing may appear between the veins, and calcium-related spotting can start showing across the plant.
Ionic Cal-Mag Pro gives your plants a fast, usable supply of Calcium, Magnesium, Nitrogen, Iron, amino acids, humic acids and organic plant extracts, helping keep growth strong, healthy and productive when demand is at its highest.

| Best For | Coco, soil, hydroponics and all grow styles |
| Prevention Dose | 0.5ml per litre |
| Correction Dose | 1ml per litre |
| Use With | Quality base nutrients |
Why Use Ionic Cal-Mag Pro?
Calcium and magnesium are secondary nutrients, but there is nothing secondary about the problems they cause when plants run short. Deficiencies can hit hard, especially in coco, soft water areas, RO water setups, and high-performance flowering programs.
Coco can hold onto calcium, leaving less available for the plant. Heavy potassium use from PK boosters can also interfere with calcium and magnesium uptake, which is exactly when your plants need everything running smoothly.
Ionic Cal-Mag Pro helps protect against those issues so your final yield does not suffer because of avoidable deficiencies.
Common Signs Of Cal-Mag Deficiency
- Yellowing between leaf veins, often linked with magnesium deficiency
- Small dark brown spots with sharper edges, often linked with calcium deficiency
- Sluggish growth during key growth or bloom stages
- General paling or yellowing of leaves
- Weak overall plant performance when demand is high

How To Use Ionic Cal-Mag Pro
| Use Case | Dose |
|---|---|
| General prevention | 0.5ml per litre of water |
| Correcting an existing deficiency | 1ml per litre of water |
Add Ionic Cal-Mag Pro to your feed water or reservoir as part of your normal nutrient mix. Always add nutrients and additives one at a time, stirring well between each addition.
Never mix nutrients, boosters or additives together in their concentrated form straight from the bottle.
Best Used In Coco And Heavy Bloom Feeding
This is where Ionic Cal-Mag Pro really earns its keep. Coco growers are more likely to run into calcium and magnesium issues, and plants being pushed hard in bloom can quickly show signs when something is missing.
If you are using strong base nutrients, PK boosters or growing under powerful lighting, adding a Cal-Mag supplement can be a smart way to keep the plant balanced and avoid silly problems late in the cycle.
Why Buy From The Hydro Bros?
The Hydro Bros stock Ionic Cal-Mag Pro because it solves a real problem growers see all the time. If your plants are hungry, fast-growing and being pushed hard, this is one of those simple additives that can save a lot of headaches before they cost you yield.
