FoxFarm Cultivation Nation® Cal-Mag

Cultivation Nation® Cal-Mag is a supplement for use during fruiting and flowering to address deficiency problems that can occur in hydroponic, soil and both small and large-scale growing environments.

How to Use:

Cover cap vent and shake well before use. Mix 1 Tbsp (15 mL) per gallon (4 L) of water. Begin use just before bud development. Continue use as needed, not more than once per week.

Maintain a pH range of 5.6 – 6.8. A pH outside this range can impact the availability of calcium and magnesium.
