Sensi Cal-Mag Xtra by Advanced Nutrients feeds your your crops the extra Calcium, Magnesium, and Iron they need If You Use a Non-Advanced Base Nutrient or when plants ask for more.
Plants - just like all forms of life, including human beings - require a complete range of essential elements in order to thrive. Not one can be lacking, or your crops may suffer nutrient deficiencies. Of course, different concentrations of different nutrients are required by plants and animals at different stages of their lives.
Just like young, developing children need vitamins and minerals, your plants need a steady supply of calcium and magnesium to ensure vigorous, healthy growth. But even expert growers often overlook another crucial element for high-value crops: specific forms of iron in precise ratios.
If you&'re using our base nutrients, your crops are already getting the correct amounts of Ca, Mg, and Fe. But if you&'re using our competitors&' base nutrients, your crops could suffer from stunted growth or yellowing leaves. In that case, use Sensi Cal-Mag Xtra - the nutrient supplement formulated with the ratios of Ca, Mg, and Fe yourcrops need.
Are you experiencing yellowing leaves or stunted growth? If so, give Advanced Nutrients Sensi Cal Mag Xtra (4-0-0) a try! It contains the added calcium (Ca), magnesium (Mg) and iron (Fe) your crops need to thrive. Specially designed for use with all hydroponic systems and media.

Exact, consistent formulation
Contains the precise ratios your plants need
Provides superior results over competeing brands
Helps make plants stronger - more productive!

Absolutely fantastic product

May 11, 2021

Absolutely great addition to go along with the Sensi A+B. I have grown for many years and thought I'd try the sensi grow line as a test. And have to say it is so simple and effective i now use sensi products exclusively to feed my plants. And the results have been great so far. I would definitely recommend this product to new and seasoned growers. And if you have issues with PH level then this product is a great solution to balance and feed your plant's at the same time. I feed 1 time a week with the sensi A+B and sensi Calmag in the same watering/ feeding. And even watering in between it still keeps a balanced ph in the growing median. Try it you will not be disappointed forget paying way over the top for FF and the big name brands and give this a try.

I've tried several cal mag plus type products. The others worked well too but this works a little better. I believe that is because of the fulvic acid in it makes adjusting ph either easier because it comes out at a certain ph with my fertilizer (canna coco) and or more efficient because I use less ph down (ascorbic acid) depending on my needs.

Used alongside my other Advanced Nutrients mixed together. Plants seem to be thriving!

January 29, 2019

I have a feeding schedule that I'm following for my autoflower cannabis plants and use a large line of Advanced Nutrients. This is one of many, that I use in certain stages. My plants are looking so good since day 1 that I'm starting to think they are legitimately perfect grows. For a 1st time home-grow, I'm stoked on my Advanced Nutrients!

I use this with the rainwater I water my plants with. Didn't realize until watching a YouTuber who does orchids say that you're plants need calmag aha rainwater doesn't provide that..I then question then how do orchids survive out in nature when the rain is their only water? Any who, I like it, no issues. I use to water all my plants now.

Need help to identify

April 25, 2021

Hey guys, I really need help. I got the calmag and I hope this will solve the problem. I've attached some pictures. They are autos so I went with half the dose. Anyone can confirm this is in fact magnesium deficiency? I'm desperate and I'm ceossing fingers this will work. Some stems wven turned purple.

I like the fact that Advanced Nutrients offers products exactly as described. I like the fact that you can count on their products to deliver consistent results every time you use them. This Cal-Mag is just what I needed and it worked just like I expected. What else is there to say? 10 out of 5 stars.

Too much nitrogen to add as a supplement. You can only really use it if you replace your “micro” style nutrient with it. I went with another brand that’s 0-0-0 shortly after getting this, which allows me to add just calcium and magnesium without nitrogen toxicity.

after 1 use i can confirm its the best I've ever seen. Plant grew green and healthy. After excessive use plant grew dark green but still healthy. This stuff is potent but won't hurt your plant if used as directed.

This stuff works as expected and as advertised. I never had any deficiency in any of my plants. My plants have a healthy green color and grow about 1 to 2 inches a day. I use Remo nutrients with this addictive.

The a.n. line of nutes have gave me supreme results, but at a cost. This calmag supplement is wonderful in your
line up. The micro, grow, and bloom trio with big bud and flawless finish at 3/4 strength max.
