Know before you buy
No, Mag-Pro is designed as a supplement to be used alongside your primary complete nutritional formula. It provides a targeted boost of phosphorus, magnesium, and sulfur rather than a balanced diet for your plants.
Purified water sources like reverse osmosis or rain water often lack the essential minerals found in tap water. Mag-Pro helps replenish necessary magnesium and sulfur that are typically stripped away or absent in these water sources.
You should introduce Mag-Pro when your plants begin the transition into the flowering or fruiting stage. Its high phosphorus content is specifically formulated to support bud development, bloom size, and fruit production.
Yes, the liquid concentrate is formulated for easy application through Hozon siphons or standard fertilizer injectors. For Hozon systems, use 0.5 to 1 ounce per gallon, or 4 to 8 ounces per gallon for a 1:100 injector ratio.
As a mineral-based supplement, Mag-Pro may slightly influence the pH of your water. It is always recommended to check and adjust the pH of your final nutrient solution after adding all components to ensure it remains within the optimal range for your specific plants.
