GT Liquid Nitrogen | Nitrogen Deficiency Corrector for Plants & Hydroponics | 250ml, 1L, 5L

Pale Leaves and Slow Growth? Your Plants Are Telling You They Need Nitrogen

Nitrogen is the most demanded mineral nutrient in plant growth — it’s the engine behind every new leaf, shoot, and cell your plant produces. When nitrogen runs low, growth stalls, older leaves turn pale yellow, and your plants lose the vigour they need to reach their potential. GT Liquid Nitrogen is a concentrated nitrogen supplement that corrects deficiency fast, restores healthy green colour, and gets your plants back on track without disrupting your existing feed programme.

Signs Your Plants Need More Nitrogen

• ⚠️ Yellowing starting on older, lower leaves — nitrogen is mobile in the plant; it moves from old leaves to new growth when supply runs short
• ⚠️ Pale green colour across the whole plant — reduced chlorophyll production makes leaves lose their deep green
• ⚠️ Slow or stunted growth — without enough nitrogen, cell division slows and new growth stalls
• ⚠️ Premature maturation — nitrogen-starved plants rush to finish early, reducing yield and quality

What GT Liquid Nitrogen Does

• ✅ Corrects nitrogen deficiency quickly — delivers immediately available nitrogen directly to your nutrient solution or growing medium
• ✅ Restores deep green leaf colour — chlorophyll production recovers as nitrogen levels normalise
• ✅ Resumes vigorous growth — plants bounce back with renewed leaf and shoot development
• ✅ Protects yield and quality — correcting deficiency early prevents premature maturation and low harvest weight
• ✅ Works alongside your existing nutrients — add to any base nutrient programme as a targeted top-up

How to Use GT Liquid Nitrogen

GT Liquid Nitrogen is a concentrate — always dilute before use. Add to your nutrient solution as a supplement when nitrogen deficiency symptoms appear, or as a preventative top-up during periods of rapid vegetative growth.

Start at a low dose and increase gradually while monitoring plant response and EC levels. Always check and adjust pH to 5.5–6.5 after adding.

Tip: Nitrogen deficiency is most common during fast veg growth when plants outpace the nitrogen supply in your base nutrient. If your plants are growing rapidly and starting to pale, add GT Liquid Nitrogen before symptoms worsen.

Choose the Right Size

• 250ml — ideal for home growers treating isolated deficiency issues
• 1L — great for regular growers keeping nitrogen levels dialled through veg
• 5L — best value for large-scale grows and commercial operations

Pair it: Use GT Liquid Nitrogen alongside GT Fulvic for enhanced uptake, and GT Silica for stronger, more resilient plants through the vegetative stage.
