Grotek Cal Max
During periods of high temperatures and accelerated growth, plants can develop nutrient deficiencies, which are preventable. Cal-Max was developed to provide the additional calcium, magnesium and iron needed to support peak production.
Applied as a foliar spray, this product can help even in environments where nutrient translocation from roots to leaves is difficult or not occurring at all. Cal-Max can be used to treat problems when they surface. It can also be used as a preventative supplement in your nutrient program to avoid deficiencies such as tip burn in lettuce and blossom end rot in tomatoes.
