NPK Industries RAW B-Vitamin with Magnesium
NPK Industries RAW B-Vitamin is a completely water-soluble plant supplement combining 1% Vitamin B1 with 9% magnesium and 12% sulfur. Its concentrated blend of thiamine mononitrate and magnesium sulfate supports chlorophyll production, photosynthesis, enzyme activity and plant nutrition during demanding stages of development.
RAW B-Vitamin can be incorporated throughout vegetative growth and flowering but is especially useful during transplanting, environmental stress, rapid growth, transition and heavy flower or fruit production.
Key Benefits
- Dual-action formula: Combines Vitamin B1 with magnesium sulfate in one concentrated supplement.
- 1% Vitamin B1: Supplies water-soluble thiamine mononitrate for metabolic and stress-related plant processes.
- 9% magnesium: Provides the central mineral required for chlorophyll formation.
- 12% sulfur: Supports amino-acid formation, protein production and enzyme activity.
- Photosynthesis support: Magnesium helps plants capture light and convert it into usable energy.
- Transition support: Complements feeding programs during transplanting, environmental stress and crop-stage changes.
- Full-cycle versatility: Suitable throughout vegetative growth and flowering.
- Completely water-soluble: Dissolves cleanly for reservoirs, irrigation solutions and properly prepared foliar sprays.
- Broad compatibility: Works with soil, coco coir, hydroponic and custom fertilizer programs.

RAW B-Vitamin is not a complete fertilizer. It should be used alongside an appropriate source of nitrogen, phosphorus, potassium, calcium and essential micronutrients.
How Magnesium Supports Plants
Magnesium sits at the center of the chlorophyll molecule and is essential for capturing light during photosynthesis. It also participates in enzyme activation and energy transfer throughout the plant.
Adequate magnesium supports:
- Chlorophyll production
- Healthy green foliage
- Photosynthetic efficiency
- Energy transfer
- Carbohydrate production
- Enzyme activity
- Balanced vegetative and flowering development
Lower-leaf yellowing between green veins can be associated with magnesium deficiency, but similar symptoms may result from improper pH, excessive potassium or calcium, root damage, overwatering or nutrient lockout.
How Sulfur Supports Plants
Sulfur is a secondary plant nutrient involved in:
- Amino-acid formation
- Protein synthesis
- Enzyme and coenzyme function
- Chlorophyll-related processes
- Nitrogen utilization
- Formation of naturally occurring aromatic compounds
RAW B-Vitamin supplies sulfur through highly soluble magnesium sulfate.
How Vitamin B1 Supports Plants
Vitamin B1, or thiamine, participates in enzyme systems associated with energy metabolism. NPK Industries formulates RAW B-Vitamin to provide additional nutritional support during demanding periods such as transplanting, environmental stress and heavy flower or fruit production.
Vitamin B1 should be viewed as a supporting supplement rather than a substitute for appropriate watering, temperature, humidity, nutrition and root-zone management.
Root-Zone Application Rate
For reservoirs, irrigation solutions and root drenches:
- Standard Rate: Add ¹⁄₁₆–⅛ teaspoon per gallon of water.
- Application Frequency: Apply as needed according to plant condition and the complete fertilizer program.
- Growth Stages: Suitable throughout vegetative growth and flowering.
- Sensitive Plants: Begin at the lower rate and monitor plant response.
RAW specialty recipes may specify different concentrations for particular situations. Only use a higher rate when following a current NPK Industries recipe or package instruction.
Recommended Application Windows
RAW B-Vitamin may be especially useful during:
- Transplanting
- Clone establishment
- Rapid vegetative growth
- Transition into flowering
- Heavy flower or fruit development
- Heat or drought stress
- Recovery from environmental fluctuations
- Periods of increased magnesium demand
Correct the underlying environmental or root-zone problem rather than relying on a supplement alone when plants are experiencing ongoing stress.
Foliar Application
The manufacturer identifies RAW B-Vitamin as compatible with foliar feeding but does not publish a separate foliar concentration on its current product page.
Follow the current package label for foliar dilution. Before treating an entire crop:
- Dissolve the product completely in clean water.
- Test the prepared spray on a small area.
- Observe the treated foliage before expanding the application.
- Apply during an appropriate low-light period.
- Provide sufficient airflow so leaves dry properly.
Do not assume that a root-zone or deficiency-correction rate is automatically appropriate for foliar spraying.
Recommended Mixing Instructions
- Fill the reservoir or mixing container with fresh water.
- Measure RAW B-Vitamin carefully.
- Pre-dissolve the crystals in a small amount of clean water.
- Stir until no visible particles remain.
- Add the dissolved mixture to the reservoir.
- Add base fertilizers in their required sequence.
- Add other compatible supplements individually.
- Mix thoroughly between each addition.
- Check the completed solution’s EC or PPM and pH before feeding.
Never mix concentrated dry fertilizer powders together unless their compatibility has been confirmed. Dissolve each product separately before combining it in the reservoir.
Using It With Cal-Mag and Other Magnesium Products
RAW B-Vitamin already supplies 9% magnesium and 12% sulfur. Account for these nutrients when combining it with:
- Cal-Mag supplements
- Magnesium sulfate or Epsom salt
- Magnesium-rich base fertilizers
- Sulfur supplements
- Hard source water containing magnesium
Unnecessary overlap can raise EC and disturb the intended balance among magnesium, calcium and potassium.
RAW B-Vitamin does not supply calcium and should not automatically be treated as a complete Cal-Mag replacement.
Growing Media and System Compatibility
RAW B-Vitamin is suitable for properly managed:
- Hydroponic reservoirs
- Coco coir
- Soil and soilless mixes
- Deep water culture
- Nutrient film technique
- Aeroponics
- Flood-and-drain systems
- Drip irrigation and fertigation
- Hand-watered container gardens
- Foliar feeding programs
- Custom fertilizer recipes
Monitor reservoir strength whenever adding concentrated magnesium or sulfur to an existing fertilizer program.
Safety and Handling
The manufacturer’s SDS classifies RAW B-Vitamin as a nonhazardous soluble nutrient. However, concentrated dust or direct contact may cause irritation.
- Avoid breathing airborne powder.
- Wear a dust mask when handling large quantities.
- Safety glasses or goggles are recommended.
- Avoid contact with the eyes.
- Wash hands after handling.
- Keep away from children and pets.
- Do not ingest.
If the product enters the eyes or contacts irritated skin, rinse thoroughly with clean water. Seek medical attention if irritation persists.
Storage Recommendations
- Store tightly sealed in the original container.
- Keep in a cool, dry area.
- Protect from moisture and humidity.
- Keep away from excessive heat, flame and direct sunlight.
- Use a clean, dry measuring utensil.
- Reseal immediately after measuring.
- Dispose of unused material according to applicable regulations.
Important Usage Notes
- RAW B-Vitamin is a supplement, not a complete fertilizer.
- Measure carefully because the formula is highly concentrated.
- Begin at the lower rate for young or sensitive plants.
- Account for the supplied magnesium and sulfur.
- Avoid unnecessary overlap with Cal-Mag or Epsom salt.
- Dissolve completely before adding to a reservoir or sprayer.
- Follow the current package label for foliar dilution.
- Monitor EC or PPM, pH and plant response.
- Diagnose persistent stress or deficiency symptoms before increasing the rate.
