Advanced Nutrients Sensi Cal-Mag Xtra Plant Nutrient, 4L

If you're using RO water you need to have this CalMag to replace the goodies that plants crave. It's totally brawndo for plants! Easy 5mls to a gallon and it will last long enough that you won't remember buying it the 1st time.

As a dedicated plant enthusiast, I've been consistently impressed with Advanced Nutrients products. Sensi Cal Mag Xtra is no exception. It has significantly enhanced the health and vitality of my plants. The user-friendly website provides valuable resources, including detailed feeding charts, to optimize plant growth. I'm so pleased with the results that I'm hesitant to experiment with other brands. If you're seeking a reliable and effective nutrient solution, Advanced Nutrients Sensi Cal Mag Xtra is highly recommended.

I've been using this along with the Micro, Grow, Bloom series of nutrients and so far everything is going great. It's part of the PH Perfect line of nutrients AN has under their label and can be used in a variety of applications whether it be soil, foliar or hydroponics. I add this once a week and my plants are looking nice and green. I like having the option of buying smaller jugs of this stuff because I don't grow more than two to four plants at a time and I'm not having half empty bottles of calmag expire because I only use so much per cycle. I think this 1 liter will last me three cycles, maybe four but the cost between this and the competition is still significantly less when purchasing this size. I think Botanicare charges ten bucks more for a quart sized bottle with less nutrients.

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.

If the seal is opened and the cap is on something's fishy. This also leaked all over because there is a hole in the plastic cap. I've used this product before from other sources and never had a hole in the plastic cap. This liquid also seems very thin. The company said they'd send me a replacement so I'll update this review when the new bottle arrives.A replacement was sent very quickly and all was good with the second bottle. I'm upping my review to four stars instead of five stars only because from what I've read this is somewhat of a problem. These bottles should be checked a little more closely. I'd buy again because they take care of their problems and deserve a second chance. Next time will surely be five stars as long as there are no leaky bottles.

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.

Sealed and no leaks!

A little goes a long way. One cap full per two gallons of water.
