miraclegro may be bad

[Cakes]

I took a trip to Walmart yesterday and looked at the new formula Miraclegro has started to use for their powder and I can no longer recommend it. They have added molybdenum and that stuff scares the living jebus out of me. My old gardening book says that more OR less than an ounce of it per acre will literally cause cows who graze there to fall down (and live no more because it makes them either stop breathing or paralyzed). So, I am afraid of it accumulating in the soil if it is used regularly on marijuana plants (or any plants meant for consumption).

both the veg formula and the bloom formula of MG have it in them. so does the veg formula for "Advanced Gardener" but their bloom formula does not.

you can look up the heavy metal content of many fertilizers at this government site:

Miracle gro is pretty shoddy stuff, but every pot growing book i've read mentions molybdenum as a needed nute, although not always found due to cost of adding it.

I use "Bio Genesis Mineral matrix Micro-nutrient supplement" which has .0005%
molybdenum and that seems like a very small amount. It is also OMRI certified so its at least halfway decent.

Not trying to say anything positive about Miracle gro I hate the stuff, I just think unless you have pure undiluted molybdenum, you have nothing to worry about.

Molybdenum is hard on ruminants. It throws off their copper levels. If you are not a ruminant you have nothing to fear from molybdenum.

:D

I Had no clue what a ruminant was until you mentioned the word and I looked it up. Good to know.

For anyone else in the dark: A ruminant is any hooved animal that digests its food in two steps, first by eating the raw material and regurgitating a semi-digested form known as cud, then eating (chewing) the cud, a process called ruminating. Ruminants include cattle, goats, sheep, llamas, giraffes, bison, buffalo, deer, wildebeest and antelope. The suborder Ruminantia includes all those except the camels and llamas, which are Tylopoda. Ruminants also share another anatomical feature in that they all have an even number of toes.

I think my dogs do that sometimes ;)

but your plants NEED molybdenum to LIVE

why are you using that salty MG anyways?


Molybdenum (Mo)a catalyst needed in small quantities. It is involved in nitrogen fixation (assimilation) and in the manufacture of enzymes.

Deficiency - causes a nitrogen deficiency. Plants are light green, malformed and stunted. Causes the "whiptale" disease where young leaves are long, narrow and severely twisted, but not tightly bunched as in the "rosetting" caused by a zinc deficiency.
Toxicity - very toxic to plants above 100 to 200 PPBillion (not much). Causes iron and copper lockup, improper nitrogen utilization

It gets used because it is easy to get.

And u are maybe onto something about the salt link. Turns out that it causes gout symptoms like the kind from preserved meats. Severity of the symptoms directly related to the length of exposure to excessive amounts. you can take huge amounts for a year and never show it but years of exposure can affect u seriously with outward signs beginning at 4 years.
