MAGNESIUM AND SULFUR BOOST

Photosynthesis is the process whereby the chlorophyll in the leaves converts sunshine and CO2 into sugars. It is the basis of ALL plant growth. No Magnesium, no chlorophyll, no photosynthesis. Sulfur aids in the formation of chlorophyll.

MAGNUM is our high potency Magnesium/Sulfur boost that will ensure an ample supply of Magnesium and Sulfur for chlorophyll synthesis.

Magnesium deficiency is the MOST common cause of poor yields besides overfeeding. The primary symptom of Magnesium deficiency is premature yellowing or interveinal fading of leaves. Sulfur deficiency is characterized by the fading of the veins.

Once yellowing is visible, CO2 consumption has slowed. That affects flower development.

• The most common cause of Magnesium deficiency is the high

Potassium/Phosphorus levels of bloom boosters.

• A secondary cause is overfeeding Calcium

If you are using Deep Breath to accelerate CO2 uptake, or you are using CO2 enrichment, the increased growth rate you expect to see will not happen if you have a Magnesium deficiency. Plants grown under normal CO2 will be even more impaired.

CAL-MAG IS NOT THE ANSWER

  • NO Cal-Mag product on the market contains sulfur
  • Magnesium and Sulfur deficiencies almost always occur together
  • Chlorophyll formation requires BOTH Magnesium and Sulfur

EXCESS CALCIUM CAN CAUSE MAGNESIUM/SULFUR

DEFICIENCY

Calcium and Magnesium are transported through the plant by similar pathways so the ratio of Calcium/Magnesium is important. The higher the ratio of Calcium to Magnesium the more the transport of Magnesium is impaired.

  • The proportion of Calcium to Magnesium in Cal-Mag products is way too high.
  • High Calcium levels “LOCK-UP” Sulfur which is necessary for the formation of Chlorophyll.

• Most Cal-Mags are loaded with Nitrogen (check the label) so you’re adding a “grow” nutrient right in the middle of bloom.

Remember, the Micro part of all 3 part base nutrient lines is loaded with Calcium so adding a Cal-Mag can lead to problems. We’ve actually seen a Cal-Mag product worsen a Magnesium and Sulfur deficient plant.

BOTTOM LINE:
TREAT A MAGNESIUM DEFICIENCY WITH MAGNESIUM AND SULFUR ONLY!

Chlorophyll deficiency in the bloom stage causes fading yellowing leaves right when flowers are putting on mass at a rapid rate. Magnum) with heavy Magnesium and Sulfur will keep a plant's energy factories optimized and the B1 helps relieve the stress caused by high performance bloom formulations.

It’s tasty but I prefer more spice. It’s dry not wet which I prefer. A little pricey.

They’re expensive, but they’re actually really good
Set name: Variety Pack Pack of 6
Honestly, these are expensive. So if you’re not picky or you don’t really care about your beef jerky, then you don’t really need this one. But if your pallet desires the finer beef jerky in life, and this is the way to go. I took a risk with it and I’m glad I did otherwise I would never have experienced this delicious taste before. I can’t describe it to you, just buy it and eat it and you’ll understand, but only if you really care what your beef jerky taste like, if you can’t tell the difference between amazing jerky and awful jerky and don’t worry about it
