Enjoy the fruits (and vegetables) of your labor! Grotek Cal-Max (2-0-0) can be used on all plants to provide added calcium, magnesium and iron. This helps solve one of the most common nutrient deficiency problems facing fruit and vegetable growers as many soils or potting mixes simply do not have enough of these nutrients to keep the hungry plants growing.

Use as part of your regular feeding program to eliminate leaf yellowing or flowers dropping off (bud abort). Also, helps prevent tip burning in lettuce and cabbage as well as blossom-end rot in tomatoes and peppers.

Available size: 1-Liter (35oz)


Soil Gardens: Mix 1 tsp per gallon of water.

Aggressive Formula: Mix 1-1/2 tsp per gallon of water.

Hydroponic Gardens: Mix 1-1/2 tsp per gallon of nutrient solution.
