Gold Label Ultra MG – Magnesium & Nitrogen Additive

Keep magnesium available across a wide pH range

Gold Label Ultra MG is a nitrogen and magnesium additive developed to perfectly balance your NPK and micro-elements through both vegetative and generative development. It uses a high-quality magnesium chelate that is easily absorbed by the crop across a wide pH range, correcting shortfalls that otherwise stall growth.

Pale leaves and slow growth from a magnesium shortfall?

Magnesium deficiency typically shows as interveinal yellowing on older leaves and sluggish growth, and it strikes fastest on media that don't hold magnesium well. Ultra MG keeps chelated magnesium available whatever your pH, correcting the shortfall whether applied continuously on inert media or as a top-up on peat and compost.

Key Benefits

• High-quality magnesium chelate absorbed reliably across a wide pH range
• Balances nitrogen and magnesium through vegetative and generative stages
• Continuous feed on inert media such as coco, rockwool and clay
• Replenishment feed on peat and compost substrates
• Corrects deficiency fast, restoring leaf colour and growth rate

How to Use

• Rate: 0.25-1ml per litre in combination with any Gold Label Base Nutrient
• Inert media: use continuously at every feed
• Peat and compost: use as a replenishment feed when magnesium runs low
• Mixing: never combine pure nutrients together, always mix each into water separately
• Shake the bottle before use and store at room temperature
