Regular CalMag should be fine, just not CalMag+ due to the synthetic chelating agent EDTA as listed on the bottle. What chelates do is make the mineral more available to the plant, essentially forcing its assimilation by the roots. Humic and fulvic acids are organic chelates and they are present in Pure Blend Pro.
The effect of using a single EDTA-containing product at low doses is probably minimal; but ideally you wouldn't want to if your goal is to create the most hospital environment for beneficial microbial populations and you also use products that contain such microbes. You can use CalMag original (they also have dry CalMag if I am not mistaken), or various alternatives including just adding more dolomite lime to your soil mix and/or fertigation solution. Botanicare also has an OMRI line of nutrients that includes two products that could be used instead of CalMag. Huvega is a magnesium formula also containing other minerals, and Calplex is a calcium carbonate formula. Both are especially good for foliar application.
It seems like the only ones graced with such information, besides the manufacturers, are the distributors and retail outlets that carry the products and let's just say they don't always relay it correctly.
They used to call it Fulvex, and it was my understanding at the time that it did contain fulvic acids but as they have changed the name of the product to Huvega it kind of lacks that implication now. Still just says "derived from magnesium sulfate", but we all know there is more to it than that.
I have no doubt that they would divulge a little additional info to those who ask, but it would be nice to see all of it on the label or even on their website. In general it is a pain in the ass to determine exactly what makes up a nutrient or supplement, just because something is listed as a 'magnesium formula' doesn't mean it lacks others elements or minerals. It seems like the only ones graced with such information, besides the manufacturers, are the distributors and retail outlets that carry the products and let's just say they don't always relay it correctly.
Again, AGREED. I just want the real content of the bottle. Do they bury the info to scam us, or to keep the content secret? Or some of both?
Whereas the product label only says "may be beneficial when used as a seedling solution, can be used in conjunction with chemical or organic nutrient solutions, ideal for use with leafy plants, vegetables and fruits". In the case of Botanicare, it is almost as if they actually over-simplify the purpose or mechanism of [some of] their products on the label.The origin of ionic minerals
Minerals are created from the oxidation of organic matter. Most Ionic materials are a fracture of extracted
Humic substances from brown lignite. The oxidation process creates a product that has a high carbon and
oxygen content and contains large amounts of free radicals due to the high amounts of oxygen - hydrogen
groups. These groups are vital in the electron transfer, which is important to ionic exchanges.
How Huvega works
• Releases minerals in soil - Huvega solubilizes substantial amounts of minerals in the soil and can enter into
complex bonds with various dissolved minerals.
• Protects plants from stresses - Huvega aids in the relief of oxygen deficiencies, which increases the
resistance to drought and other environmental stresses.
• Stimulates antibiotic protection - Natural antibiotics such as streptomycin, terramycin, and penicillin are
produced during the decomposition of plant residue. Huvega and other phenolic substances enhance the
uptake and translocation of such antibiotics in plants.
• Reduces wilting - Huvega helps the plant accumulate soluble sugar which increases osmotic pressure in the
cell walls and enables them to withstand wilting.
• Increases DNA metabolism - Huvega increases the activity of several enzymes including those involved with
metabolizing RNA and DNA.
• Promotes high crop yields - Treating seeds with low concentrates of Huvega before sowing, improves their
rate of growth, development of roots and shoots and increases crop yield.
