## Overview

Advanced Nutrients Sensi Cal-Mag Xtra is a 500 mL liquid supplement delivering perfectly balanced calcium, magnesium, and iron to support vigorous plant growth in soil or hydroponic systems. Trusted by expert growers, it requires no assembly and ensures nutrient consistency for healthier, greener crops.

## Description

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 Extra - the nutrient supplement formulated with the ratios of Ca, Mg and Fe your crops need.

Review: Good stuff!! - 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.
Review: It’s Advanced Nutrients, everything they make is perfect - 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.
