Humboldt County's Own Magnum - Magnesium/Sulfur Supplement with Vitamin B1 - 1 Gal

Magnesium Support for Heavy Feeding Cycles - 1 Gal

Magnesium sits at the center of the chlorophyll molecule, so a shortfall slows photosynthesis and limits plant growth. Heavy flowering feeds with high potassium can make that shortfall more likely. Magnum is a magnesium/sulfur supplement with vitamin B1 that adds magnesium back into your feed program, and it is made to work with popular base nutrients.

The 1 Gal bottle suits home gardeners and small indoor rooms that want to correct or prevent magnesium deficiency without buying in bulk. Commercial growers can use it as a targeted supplement alongside a larger program.

Key Features & Benefits

• Magnesium/sulfur formula — supplies magnesium that plants need for chlorophyll synthesis.
• Vitamin B1 included — helps ease stress during demanding flowering regimens.
• Base nutrient compatibility — works well with popular base nutrients, so it fits your existing program.
• Magnesium-only approach — targets magnesium without adding other nutrients to the feed.

Who Should Use Humboldt County's Own Magnum

Growers running high-potassium flowering boosters, growers whose base nutrients lack enough magnesium, and growers with demanding varieties will find it useful. Check your base nutrient label to see how much magnesium it already supplies.

Frequently Asked Questions

Q: What does magnesium do for plants?
A: Magnesium is the central atom in chlorophyll. Without enough of it, plants cannot photosynthesize efficiently, and growth suffers.

Q: How do I recognize a magnesium deficiency?
A: The usual sign is premature yellowing or fading between the leaf veins. By the time it shows, development has often already been affected, so prevention is easier than correction.

Q: Why can high-potassium boosters cause deficiency?
A: High potassium levels are a common cause of magnesium deficiency. Growers using strong flowering boosters should watch magnesium supply closely.

Q: Is a cal-mag product the same thing?
A: No. Cal-mag products add calcium, and excess calcium can interfere with magnesium uptake. Check labels, and use a magnesium-only supplement when magnesium is the problem.

Q: Will it work with my base nutrients?
A: It is designed to work well with popular base nutrients. Follow the label for dosing and confirm your feed program's existing magnesium level first.
