HGK Nutrient Schedule

• Introducing the newest addition to the HGK nutrient range, the HGK Cal-mag! Designed to supplement our 3 part formula of Gorilla Grow I, Mass Bloom II and Overload III for fruiting or flowering plants, but can be added to most nutrients as a stand alone product.
• We highly recommend using our Cal mag like a A&B with our Gorilla Grow I and Mass Bloom II formulas. 
• Whether your plants are looking a little yellow or you simply want to prevent any possible problems, the addition of a cal-mag supplement can help reduce yellowing by preventing deficiencies before they happen. While the HGK range already has cal-mag incorporated into it sometimes they just need a little more.
