Calcium and Magnesium, the Organic Way

Yellowing between the veins, rusty spots and weak new growth are among the most common problems indoor plants show, and most are a shortage of calcium, magnesium or iron. Soft water, rainwater, coco and LED lighting all make those shortages more likely.

OG Organics Sensi Cal-Mag Xtra is Advanced Nutrients' certified organic version of their best-selling cal-mag (OMRI and CDFA-OIM listed). It supplies calcium, magnesium and iron in plant-available forms, so it can be used to prevent problems or to correct them.

Why It Works

Calcium: builds strong cell walls and healthy new growth
Magnesium: the centre of every chlorophyll molecule, for deep green leaves
Iron: prevents pale new leaves
Certified organic: OMRI and CDFA-OIM listed

For Houseplant & Garden Growers

Watering with rainwater or filtered water, growing under an LED light or using a coco-based mix? Those are the setups where houseplants such as Calathea, Monstera and citrus most often run short. A regular dose keeps leaves green.

For Growers

Dose: 2ml per litre
To correct a deficiency: 2ml per litre, repeating after a week if needed
Foliar: 2ml per litre as a leaf spray for faster results
Mixing: add it to the water first, before your base feed

🌿 Rose's Pro-Tip: If new leaves are pale, it's usually iron or magnesium. If old leaves yellow between the veins, it's magnesium. A cal-mag with iron covers both.
