Sensi Cal Mag Xtra® – Discover the Missing Ingredient No Other Cal-Mag Product Contains

Addressing nutrient deficiencies is no walk in the park. 

And if you’re like most growers, you’ve probably spent one too many hours pouring over forum posts, just to get to the bottom of your latest grow room mystery. 

We get it. Your cannabis is your lifeline . . . 

And the last thing you want is to get your hopes slashed by the first sight of unsightly yellowing leaves. 

But it gets even worse . . . 

Because not only do you have limited time to restore your crop before it grows weaker . . . 

You Can’t Be 100% Sure What’s Causing them to Deteriorate!

Let’s face it . . . 

Unless you’ve got a Ph.D. in horticulture, it can be nearly impossible to know exactly what your plants need. 

In fact, even growers with years of experience still call us to help them diagnose their most recent deficiency. 

And that’s okay . . . 

Because you shouldn’t have to be a plant doctor to fix common grow room problems! 

Now . . .

What if I told you there was a way you could stop the frantic guessing . . . 

And NEVER have to waste precious time again trying to remedy nutrient deficiencies?

Well, that’s the exact relief you can expect when you put . . . 

The Industry’s Breakthrough Cal-Mag Biostimulant to Work for your Cannabis!

It’s called Sensi Cal Mag Xtra®.

It’s the most comprehensive first aid kit designed specifically for the kinds of plants you grow . . .

And it’s the only Cal-Mag biostimulant you’ll EVER need to correct nutrient deficiencies in your crop. 

Because here’s the thing . . . 

With Sensi Cal Mag Xtra, you’re getting an abundance of calcium, magnesium and chelated iron . . . Which can do wonders for your plants. 

They ensure your root zone absorbs optimal nutrition

And they stop common nutrient deficiencies in their tracks . . . 

Transforming your plants back into the champion producers you desperately need them to be. 

But you’re also getting so much more than that.

Look, the reality is . . .  

Most Cal-Mag Biostimulants Are Designed for . . . Tomatoes!

And they lack the additional nutrients your cannabis is starving for. 

And just like you wouldn’t feed your dog fish food . . .

You shouldn’t feed your complex plants a solution made for a vegetable. 

At least, you wouldn’t be doing your crop any favors. 

In fact, if you’ve ever used a generic Cal-Mag biostimulant. . . only to watch your garden’s condition worsen over time . . . 

It could very well be another nutrient deficiency you haven’t yet discovered! 

Which is why when you use Sensi Cal Mag Xtra, you’re also getting . . . 

Valuable Micronutrients Your Plants Must Absorb If They Want a Fighting Chance!

Remember, calcium and magnesium are NOT the only nutrients your cannabis plants could be lacking. 

For starters, they  could be hungry for more iron . . . 

ESPECIALLY if you’re growing in coco coir. 

Even though it’s a fantastic growing medium, coco coir naturally binds to iron . . . 

Preventing your plant from absorbing this essential nutrient. 

Which is why we use chelated iron, which cloaks itself from the binding forces of coco coir. 

What’s more . . .

Your plants also need optimal ratios of manganese and zinc…

Or else you risk getting underdeveloped buds that leads to disappointing yields. 

Now, as you can see, even if we stopped there . . . 

Your plants would already benefit from a more robust range of nutrients than with any other Cal-Mag biostimulant. 

But delivering exceptional results is embedded in our Advanced Nutrients DNA.

And if we can provide even more support to your crop, we won’t stop at anything to engineer the perfect solution. 

Which is why . . . 

We’ve Fortified Sensi Cal Mag Xtra® with Kelp for an Added Boost of Game-Changing Benefits

An all-natural powerhouse for fueling optimal cannabis performance. 

You could have the most sophisticated nutrient lineup in the world. 

But if you don’t include kelp in your routine, you’re missing out on crucial benefits every top grower enjoys.

Benefits like . . .

  • A robust range of vitamins and minerals . . . The secret ingredients behind smooth and effective plant processes . . . That your plants could be lacking! 
  • Creating optimal conditions to strengthen the root zone . . . So your underground network has everything it needs to support heavy yields of full, potent bud

And when you put kelp, critical micronutrients, and chelated calcium and magnesium in one bottle . . . 

You’ll compensate for any deficiencies without spending hours wracking your brain for the answers. 

So, it’s easy to see why . . .

Sensi Cal Mag Xtra® is a Must-Have for the Serious Grower

Over time, components within the nutrients settle on the bottom of the bottle. When you pour a bottle without shaking it, you can potentially be pouring out an unbalanced solution. Shaking up the nutrient bottle ensures you are pouring the right blend into your reservoir, giving your crops the nutrition they need.

Usually, it’s not a problem. But some products are incompatible with each other and can damage your plants when they’re used together. For example, bloom boosters with high PK numbers or low-grade silica products can destabilize your nutrient mix and cause nutrient lockout.

Nutrient manufacturers design their products to be used with each other. In doing so, they include specific portions of each nutrient in each product, so crops receive the right nutrition through each stage of the grow cycle. When you stick with one manufacturer, you don’t have to worry about inadvertently destabilizing your nutrient mixture. One example of why you need to stick with only one manufacturer’s products is Advanced Nutrients’ pH Perfect line. These products are designed to keep your crops’ root zone within a specific pH range. When you use them alongside products from another manufacturer, we can’t guarantee your root zone will maintain its optimal pH level.

Advanced Nutrients has spent many thousands of man-hours developing a technology that automatically balances your pH for you — putting it in the “sweet spot” and holding it there for one week.

And the technology is so “smart” that it can account for many of the aforementioned variables in your grow room. Our proprietary pH buffering agents and stabilizing mechanisms became the foundation of a new system aptly called pH Perfect® Technology. Learn all about it here.
