Humboldt County's Own Magnum - 5 GAL

Description

Magnum is Humboldt County's Own magnesium and sulfur supplement for the flowering cycle. High-phosphorus and potassium bloom boosters and extra calcium can push plants into magnesium and sulfur deficiency, which shows as early yellowing or fading between the veins. Chlorophyll needs both nutrients, so Magnum supplies them together.

  • Supplies magnesium and sulfur together
  • HCO notes magnesium and sulfur deficiencies almost always show up together
  • Size: 5 gallons (18.9 L)
  • Rate: 1 tsp (5 ml) per gallon of water throughout the flower cycle
  • For soil and hydro
