During periods of high temperatures and accelerated growth, plants can develop preventable nutrient deficiencies. Cal-Max was developed to provide the additional calcium, magnesium and iron needed to support peak production. Cal-Max can be used to treat problems when they surface and it can also be used as a preventative supplement to your nutrient program to avoid deficiencies such as tip burn in lettuce and blossom end rot in tomatoes.

Directions for use:
