Stronger stems. Healthier growth. Happier plants.

Lotus Pro Series Cal-Mag delivers a premium, highly available source of calcium and magnesium — two essential secondary nutrients that keep plants growing balanced and strong. It’s especially important for coco-based grows, where Cal-Mag support isn’t optional, it’s required.

Why Growers Add It:

• Provides readily absorbed calcium and magnesium for healthy development

• Helps support strong stems, vibrant leaves, and consistent growth

• Essential for coco grows, where these nutrients can run low fast

• Pairs easily with your base nutrients as a targeted supplement

If you’re seeing tired leaves, weak structure, or just running coco, Cal-Mag is a simple way to keep your plants on track.
