• Feed your plants the extra Calcium, Magnesium and Iron they need if you use a non-Advanced base nutrient.

  If you're using Advanced Nutrients base nutrients your plants are getting the correct amounts of Ca, Mg and Fe. But if you're using another base nutrient your plants 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 your plants need.

  Directions
  Use 2ml per litre to correct deficiencies. Repeat after 1 week, if necessary.
