GROTEK CAL-MAX

Provides added calcium, magnesium and iron

NPK: 2-0-0

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.

Works to charge soilless media and bring plants back from common minor nutrient deficiencies resulting from nutrient imbalance, rapid growth, or overly humid conditions. 

During periods of high temperatures and accelerated growth, plants can develop preventable nutrient deficiencies. 

Directions for use:

SHAKE WELL before using.

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