Add calcium, magnesium and iron to plants that they need when using basic nutrients.
Plants - just like all life forms, including humans - require a full range of basic elements to grow. None of these can be missing, or your plants may suffer from nutrient deficiencies. Plants and animals naturally require different concentrations of different nutrients at different stages of life.
Just like small, developing children need vitamins and minerals, plants need a constant supply of calcium and magnesium to ensure strong, healthy growth. But even experienced growers often overlook another key element to high-quality crops: specific forms of iron in precise ratios. If you use our base nutrients, your plants are already getting the right amount of Ca, Mg, and Fe. But if you use our competitors' base nutrients, your plants may suffer from slowed growth or yellow leaves. In this case, use Sensi Cal Mag Xtra - a nutrient supplement formulated with the ratio of Ca, Mg, and Fe your plants need.
