DERIVED FROM

Magnesium Nitrate • Magnesium Oxide

Premium-grade materials ensure maximum solubility and nutrient availability for immediate plant uptake.

THE ROLE OF MAGNESIUM IN PLANTS

Magnesium is a critical nutrient that serves multiple essential functions:

🌿 Chlorophyll Core Component

Magnesium sits at the center of every chlorophyll molecule, making it indispensable for photosynthesis. Without adequate magnesium, plants cannot produce the energy they need for growth.

⚡ Enzyme Activation

Activates more enzymes than any other nutrient, including those involved in:

  • Carbohydrate metabolism
  • Protein synthesis
  • Energy transfer (ATP formation)
  • DNA and RNA production

🔄 Nutrient Transport

Facilitates the movement of phosphorus throughout the plant and aids in the uptake and utilization of other nutrients.

🌱 Deficiency Symptoms

  • Interveinal chlorosis (yellowing between leaf veins)
  • Starts on older leaves first (mobile nutrient)
  • Leaf margins may curl upward
  • Premature leaf drop
  • Poor fruit set and quality
APPLICATION RATES & DIRECTIONS

Magnesium Nitrate can be applied through various methods for maximum flexibility and effectiveness.

🌱 General Application Rates

Application Method Rate Frequency Notes
Soil Drench 1-2 tsp/gallon Every 2-4 weeks Apply to moist soil
Hydroponics 0.5-1 tsp/gallon Continuous in solution Monitor EC levels
Foliar Spray 1 tsp/gallon Every 7-14 days Spray early morning
Fertigation 2-4 lbs/acre Weekly during growth Through drip systems

🥬 Crop-Specific Applications

Crop Type Soil Application Foliar Rate Critical Timing
Tomatoes 2 tsp/gallon 1 tsp/gallon Flowering & fruit set
Leafy Greens 1.5 tsp/gallon 0.5 tsp/gallon Throughout growth
Citrus 3 tsp/gallon 1.5 tsp/gallon Spring & fall
Cannabis 1-2 tsp/gallon 1 tsp/gallon Weeks 3-6 of flower

💧 Hydroponic Nutrient Solution

System Type PPM Target Magnesium Nitrate Rate Notes
NFT/DWC 50-80 ppm Mg 0.5-0.8 tsp/gal Adjust based on water analysis
Ebb & Flow 60-100 ppm Mg 0.6-1 tsp/gal Higher for fruiting crops
Drip/DTW 80-120 ppm Mg 0.8-1.2 tsp/gal Account for runoff
Mixing Instructions:
  1. Always add to water, never water to powder
  2. Use warm water for faster dissolution
  3. Stir thoroughly until completely dissolved
  4. Can be tank-mixed with most fertilizers
  5. Avoid mixing with high phosphate concentrates

FREQUENTLY ASKED QUESTIONS

Click on each question to see the answer.

When should I use magnesium nitrate vs Epsom salt?

Magnesium nitrate is ideal when you need both nitrogen and magnesium, especially during vegetative growth and early flowering. It's also preferred in hydroponic systems due to complete solubility. Epsom salt (magnesium sulfate) is better when you only need magnesium and sulfur, particularly during late flowering when additional nitrogen isn't desired. Both are excellent magnesium sources; the choice depends on your nitrogen needs.

How quickly does it correct magnesium deficiency?

Foliar application shows results within 3-7 days, with new growth appearing green and healthy. Soil applications take 1-2 weeks for visible improvement. The interveinal chlorosis (yellowing between veins) on affected leaves may not fully recover, but new growth will be healthy. For fastest results, combine foliar spraying for immediate relief with soil application for long-term correction.

Can I mix it with calcium fertilizers?

Yes, but with precautions. In dilute solutions (working strength), magnesium nitrate can be mixed with calcium nitrate. However, in concentrated stock solutions, they should be kept separate to prevent precipitation. For best results, add them to your reservoir or spray tank separately, allowing each to dissolve fully before adding the next.

What's the ideal magnesium to calcium ratio?

The optimal Ca:Mg ratio is typically 3:1 to 4:1 for most crops. However, this can vary: tomatoes prefer 3:1, leafy greens do well at 4:1, and some crops like peppers can tolerate 2:1. Always consider your water source – hard water is often high in calcium, requiring more magnesium to balance, while RO water needs both added in the proper ratio.

Poor customer service

The directions for dilution on the bag are for 100 gallons. I emailed to ask for a smaller ratio of product to water and was told to use 1-2 pounds per tree. No advice on how often, whether to use diluted or dry, and it took three days to get a response. Not a great experience. I'll buy some Epsom salts next time.
