Advanced Nutrients Sensi Cal-Mag Xtra

Product detailed description

Sensi Cal-Mag Xtra is a calcium and magnesium supplement from Advanced Nutrients for growers who want to prevent deficiencies of these elements. It is especially suitable for coco and soft or reverse water, where the plant often lacks calcium and magnesium, both in vegetative growth and in bloom.

What Sensi Cal-Mag Xtra provides

The product has NPK 4-0-0 and supplies chelated calcium and magnesium, supplemented with chelated iron, manganese and zinc. Calcium is a building block of cell walls and magnesium is at the centre of chlorophyll, so an adequate supply is reflected in the strength of tissues and the richness of leaves. The chelated form ensures that the plant can easily take up the elements, even if you feed it with fertiliser that does not contain them itself in the ideal ratio.

When and how much to dose

You dose Sensi Cal-Mag Xtra at 2 ml per litre and, if needed, repeat after a week; the same dose applies for correction and for regular preventive addition. You use it in vegetative growth and bloom, indoors and outdoors. It works in hydroponics and in coco and is also compatible with competing fertilisers.

When and with what to use it

Cal-Mag runs alongside your base nutrition as an ongoing safeguard against deficiency. In coco and soft water, include it right from the start; in soil, as needed. It complements base fertilisers, for example pH Perfect Sensi Grow A+B in growth and pH Perfect Sensi Bloom A+B in bloom. If the deficiency has already shown itself through yellowing and you need to correct it quickly, reach for Revive instead.

Frequently asked questions

Why do I need Cal-Mag in coco?
Coco substrate and soft or reverse water contain little calcium and magnesium, so the plant can easily slip into deficiency. Sensi Cal-Mag Xtra adds these elements in a chelated, easily absorbable form. Dose 2 ml per litre and include it in coco right from the start of growing as a preventative measure.

How much Cal-Mag should I dose and how often?
The dose is 2 ml per litre and remains the same for correction and for regular addition. Repeat it after a week if needed. You use the product continuously in vegetative growth and bloom, indoors and outdoors, and add it to the watering together with the base nutrition.

What is the difference between Cal-Mag and Revive?
Sensi Cal-Mag Xtra is used for prevention - it supplies calcium and magnesium continuously so that deficiency does not occur at all. Revive, on the other hand, is a rescue when deficiency or stress has already shown itself through yellowing leaves. In coco and soft water, Cal-Mag runs from the start, while Revive is used specifically when a problem appears.
