Product Description


Cal-Max Provides added calcium, magnesium and iron

NPK: 2-0-0


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 in hydroponic growing. 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:

SHAKE WELL before using.

Hydroponics: Use 5 - 8 ml of Cal-Max per 4 L of nutrient solution.
