Can I foliar spray with Cal-Mag Plus?

Yes you can foliar spray with Cal-Mag Plus and it is a great way to quickly correct deficiencies during the vegetative and transition phases. We do not recommend applying any product via foliar spray late into the flower cycle when growing tight flowers, as excess moisture can lead to mold and mildew. Apply at the rate of 5 ml (1 tsp) per gallon a maximum of twice a week.
