  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!

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!


  Need help to identify

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.

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.

This product saved my crop! Having filtered water my plants were suffering from deficiencies in micro nutrients. Showing rust colored spots on all the big leaves. This stopped the madness.
