32oz - Silver Bullet utilizes sulfur, which is an essential nutrient that aids in terpene and oil production in plants. It promotes vigorous, healthy growth in the vegetative growth stage as a foliar spray and aids in both terpene and resin production as a root drench in the flowering stage. Sulfur deficiency can cause new leaves to look yellow or pink, reduced foliar growth, and cause serious damage to your plants. Prevent or treat a sulfur deficiency with Silver Bullet!
