OG Organics Sensi Cal Mag Xtra® — Correct Nutrient Deficiencies and Restore Your Plants Lush, Vibrant Nature Before It’s Too Late!

Ask any grower the benefits of an organic feeding program, and they’ll likely mention the slow release of nutrients into their plants.

This gradual release helps prevent nutrient burn from overfeeding…

And if everything else goes according to plan, that could mean finishing your cycle with a vibrant green harvest of well-fed buds.

However, there’s another side to the coin

And you must be aware of it.

You see…

It Typically Takes Longer For Your Plants to Absorb Organic Inputs

Because once they reach your root zone, they need to break down into plant-available form.

And while over-feeding is a real issue for your flowers, nutrient deficiencies can be just as devastating to your yields.

Imagine how frustrating it can be when you’re half-way through the bloom phase, and your flowers send out their very first warning sign that they’re lacking critical nutrition.

With only a few weeks left to go…

It could be too late. 

Even if you do try adding nutrients to the mix, your plants may not be able to absorb them fast enough to resolve the problem…

You could end up losing six-plus weeks of effort and diligence to damaged, unsellable yields.

And just as frustrating…

You Could Be Left Scrambling to Identify Which Nutrient Your Plants Are So Desperately Craving!

Because here’s the thing…

Oftentimes, a grower will reach for a Cal-Mag supplement at the first sight of yellowing leaves or slowed growth of their high-value crops.

However, calcium and magnesium may not be the only nutrients your plants are lacking.

After careful research, our scientists determined that your specific plant genome also craves…

  • Iron (especially for coco coir growers)
  • Additional micronutrients, like manganese or zinc
  • A wide range of vitamins

And not only that…

Your Crops Need Chelated Nutrients That Are Easier to Absorb!

The reality is, most micronutrients aren’t readily available to your plants.

You see, iron and zinc have a positive charge, and the pores on your plants have a negative charge.

And those positively charged micronutrients can’t pass through the negatively charged pores.

Which is exactly why you need chelates.

Now, pay close attention, because for your plants to reach and sustain peak performance, you need to understand this.

These chelates bond to a micronutrient, surrounding individual ions and changing the charge to negative or neutral.

And by changing the charge, those essential micronutrients are able to enter your plant’s pores.

Imagine what a relief it’ll be when you’re well into your bloom phase, and your plants have a robust range of micronutrients they can more easily absorb.

By avoiding nutrient deficiencies, you’ll enjoy the kind of explosive yields so many organic growers never get to experience.

Which is why…

We Developed The Ultimate Organic Solution to Stop Nutrient Deficiencies in Their Tracks! 

It’s called OG Organics™ Sensi Cal Mag Xtra®…

And it’s the most comprehensive way to ensure your plants get all the nutrients they need to thrive.

When you add it to your growing system, your plants will benefit from…

  • Multiple forms of calcium and magnesium (never worry about locking these critical micronutrients out of your garden again)
  • Chelated iron — an essential and often overlooked micronutrient your crops need to thrive… Plus chelated zinc
  • Kelp, an organic powerhouse that’s chock-full of the amino acids, vitamins and minerals your plants love

Imagine reaping all the benefits
of a fully organic feeding program…

While never worrying about nutrient deficiencies slowing down your plants growth.

Because, through advanced chelation, your plants will absorb all the micronutrients they need to flourish.

And you’ll grow lush, green gardens with buds that swell from the earth’s bountiful nutrition.

It’s why, for organic growers in 117+ countries, using OG Organics Sensi Cal Mag Xtra is the no-brainer for correcting nutrient deficiencies in their gardens.

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.
