Botanicare Cal-Mag Plus 2-0-0: Calcium, Magnesium & Iron Plant Supplement – 1 qt

Boost plant nutrition with Cal-Mag Plus 2-0-0

Botanicare Cal-Mag Plus 2-0-0 is a fortified blend of calcium, magnesium, and iron designed to support balanced nutrition in a wide range of growing systems. Rather than a single ingredient fix, it pairs essential minerals to help address common imbalances that can occur in hydroponic or soil environments.

Why you might reach for Cal-Mag Plus

Calcium helps strengthen cell walls, magnesium supports photosynthesis, and iron assists chlorophyll production. When using reverse osmosis water or coco coir based media, plants may exhibit calcium or magnesium draw, making a targeted supplement like Cal-Mag Plus a practical part of your feeding plan.

• Highly fortified formula containing calcium, magnesium, and iron to support nutrient balance.
• Helps address common deficiencies that can arise with certain water sources and media.
• Suitable across vegetative, transition, and bloom stages to support ongoing growth.
• Recommended when combining with RO water or coco coir media to compensate for mineral draw.
• Can be applied as a foliar spray for additional coverage and rapid uptake.
• Backed by Botanicare's expertise in plant nutrition and grower support.

How to use Cal-Mag Plus

• Mix rate and schedule based on your nutrient program and plant needs; start with a modest dose and adjust.
• Apply through root feeding as part of your regular nutrient program, or use as a foliar spray during the light cycle for best coverage.
• Monitor plant response, adjusting dosage if signs of imbalance appear.

Real-life use scenarios

Growers often turn to Cal-Mag Plus during periods of intense growth or when using RO water, seeking more consistent nutrient balance. In coco coir setups, where mineral draw can be more pronounced, Cal-Mag Plus is a common companion to base nutrients, helping maintain steady performance across growth stages.
