GS Plant Foods Cal-Mag Extreme Liquid 1 Qt – Calcium, Magnesium & Trace Elements

Plants rely on a balanced mix of nutrients, and even with the right N-P-K ratios, gaps in calcium, magnesium or trace minerals can limit growth. GS Plant Foods Cal-Mag Extreme Liquid delivers a thoughtfully balanced blend designed for fast uptake, helping to support robust plant health across growth stages.

This formula combines calcium, magnesium, iron and sulfur with essential trace elements—manganese, zinc, boron and molybdenum—supplied in an immediately plant-available form with natural chelates. The result is a versatile additive that works with a variety of irrigation styles and growing media, offering options for both root systems and leaf tissue.

Fast-acting, versatile nutrition

Cal-Mag Extreme Liquid is designed to integrate with water-soluble feeding programs. It mixes easily with irrigation water and is suitable for foliar spraying, providing an optional route for rapid leaf uptake when growth or stress signals call for quick support. The chelated minerals are chosen to enhance absorption through both roots and foliage, helping nutrients reach active sites of growth.

• Immediate plant-available minerals: Calcium, Magnesium, Iron and Sulfur support cell structure, enzyme activity and overall vigor.
• Comprehensive trace elements: Manganese, Zinc, Boron and Molybdenum help unlock nutrient pathways and support balanced metabolism.

Versatile across growing systems

Whether you grow in soil, containers, coco or hydro, Cal-Mag Extreme is formulated to mix with water for irrigation or to be used as a foliar spray. This makes it a practical option for routine feeding as well as targeted leaf applications during key growth moments.

• Soil and container ready: Suitable for traditional pots and garden beds.
• Coco and hydro compatible: Supports soilless and recirculating nutrient solutions.

Practical use tips

Start with small batches to observe how your plants respond, then adjust as needed based on crop type and growth stage. Mix evenly in water and apply under moderate temperatures and appropriate light to minimize leaf burn. Always follow label directions and monitor plant response over time for best results.
