Advanced Nutrients Sensi Cal-Mag Xtra (10 L): Hydroponic Cal-Mag Supplement
Advanced Nutrients Sensi Cal-Mag Xtra (10 L) supplies the calcium, magnesium, and iron that hydroponic reservoirs miss when the water source runs low on dissolved minerals. Calcium handles cell wall development and active nutrient transport across root membranes — plants with calcium shortage stop moving nutrition even when the feed chart looks correct. Magnesium sits at the center of every chlorophyll molecule and powers the enzymatic reactions behind photosynthesis. Iron drives new growth, chlorophyll synthesis, and the electron transport chain. The Xtra formulation adds extra micronutrients on top of the core cal-mag-iron base, which is why it's the supplement that drops into the Sensi lineup when plants are showing interveinal chlorosis or tip burn.
Built for the Sensi Line and Any Base Nutrient Running Low on Cal-Mag
Sensi Cal-Mag Xtra was formulated to integrate with Advanced Nutrients' pH Perfect Sensi Grow and Sensi Bloom base nutrients, but it works with any hydroponic feed program running RO water or a well source that tests low on calcium and magnesium. At the 10-liter size, the jug fits a mid-scale room that consumes cal-mag consistently through veg and bloom — past the point of 1 L trial bottles but before a grower needs to step up to 23 L or 57 L commercial totes. Dose as a supplement to the base feed, not as a replacement for it.
Key Features
- Calcium for Cell Wall Development: Supports cell structure and active nutrient transport across root membranes — calcium shortfalls stop nutrient movement.
- Magnesium for Chlorophyll: Central atom in every chlorophyll molecule and driver of photosynthesis-related enzyme activity.
- Iron for New Growth: Powers chlorophyll synthesis and electron transport — iron shortage shows up as interveinal chlorosis on new leaves.
- Xtra Micronutrient Package: Extra micros on top of the cal-mag-iron base cover the secondary shortages that appear in soft or RO water.
- 10-Liter Mid-Scale Size: Fits a multi-light room that consumes cal-mag steadily through veg and bloom without jumping to commercial-tote volume.
