Humboldt County's Own Magnum with Vitamin B1 is a potent magnesium supplement for preventing or treating Magnesium deficiency in plants. Magnesium is the critical element in the chlorophyll molecule which drives all the energy processes in a plant. High demand for magnesium in the blooming stage can cause fading green leaves due to chlorophyll deficiency right when flowers are putting on mass at a rapid rate. Magnum will keep a plant’s energy factories optimized while the vitamin B1 helps to relieve the serious stress that can potentially be caused by high performance bloom formulations.
