CAL MAX 500ML GROTEK

During periods of high temperatures and accelerated growth, plants can develop preventable nutrient deficiencies. Cal-Max was created to provide the additional calcium, magnesium and iron needed to support maximum production. Cal-Max can be used to treat problems as they arise and can also be used as a preventative supplement to your feeding program to prevent deficiencies such as leaf spot in lettuce and blossom end rot in tomatoes.
