Sensi Cal Mag Xtra. By Advanced Nutrients. 

Most growers only think about calcium and magnesium when their leaves start curling up like a dried crisp or yellowing faster than a discount houseplant at the back of a garden centre. But if you're relying solely on standard feeds, your plants are missing out on some of the most critical tools for reaching their full genetic potential. Enter Advanced Nutrients Sensi Cal-Mag Xtra - the unapologetically over-engineered additive designed for growers who want to prevent deficiencies, not react to them. 

Cal Mag Redefined. 

This isn’t some dusty old Cal-Mag formula repackaged to look modern. Advanced Nutrients Sensi Cal-Mag Xtra is an advanced, bioavailable cocktail of calcium, magnesium, iron, and 20 L-form amino acids - each one selected for its specific physiological function. It’s a product forged in the minds of horticultural scientists and tested by real-world growers, from modest stealth setups to industrial-scale fruiting facilities. In short, this is Cal-Mag redefined.

Increased Resistance to Pests.

Let’s start with the fundamentals. Calcium, as anyone who passed GCSE Biology might recall, is crucial for building strong cell walls. It’s the bricks and mortar of plant tissue, and without it, your crop is basically a soft-bodied liability. But Advanced Nutrients Sensi Cal-Mag Xtra takes calcium’s role a step further - enhancing nutrient movement within the plant, increasing resilience, and hardening your crop against stress, pests, and weak structural development.

Premium Nutrition. Premium Flavours.

Then there’s magnesium, the often-forgotten middle child of plant nutrition. Magnesium is the central atom in chlorophyll molecules, the green pigment that captures light and drives photosynthesis. In essence, magnesium is the component that turns photons into food. Without it, your plant’s energy system slows to a crawl. With it - and in the right chelated form as in Sensi Cal-Mag Xtra - the result is rich green growth, efficient light conversion, and a photosynthetic process running at full throttle.

Super Easy to Use. 

What you get is a fast-acting, fully soluble formula that works seamlessly through your root system or as a foliar spray. Dosage is a simple 2ml per litre - no guesswork, no complex rituals. Use it during both the vegetative and flowering phases, and your plants will thank you in stem girth, leaf vitality, and output quality.

Advanced Nutrients Sensi Cal-Mag Xtra is more than a supplement - it’s a systemic upgrade. If you’re growing indoors under intense lights, running hydroponic systems with precision, and expecting commercial-grade results, this isn’t optional. It’s essential. When the difference between good and exceptional comes down to cellular performance, you don’t leave that to chance - you leave it to Sensi Cal-Mag Xtra.
