Advanced Nutrients - The Med Deception
Recently (June 2010) Advanced Nutrients made this announcement via PR Newswire (www.prnewswire.com).

“SEATTLE, June 3 /PRNewswire/ -- In a landmark decision, Oregon regulators have given first-ever official US approval to a brand of medical marijuana hydroponics nutrients.

Oregon and most other states have regulatory agencies that examine fertilizers and hydroponics plant supplements to determine the legitimacy, ingredients and effectiveness of plant growth products.​

Advanced Nutrients co-founder Michael Straumietis welcomes the news that Oregon's government proffered formal approval for an Advanced Nutrients formula designed for a specific strain of medical marijuana.​

"Regulatory approval is a breakthrough for the medical marijuana community," Straumietis explains. "For the first time, government regulators have examined and affirmed the use of crop-specific medical marijuana hydroponics nutrients."​

Until Straumietis asked regulators to evaluate the medical marijuana effectiveness and safety of Advanced Nutrients hydroponics formulas, regulators nationwide had apparently never considered how hydroponics nutrients specifically affect medical marijuana crops.​

''It hasn't been part of the discussion, until now,'' Straumietis explains. "For example, when fertilizer regulators evaluate fertilizers that have labels claiming to produce larger tomatoes, they require specific efficacy data proving those claims. Now Oregon regulators have opened the door for formal evaluation of hydroponics nutrients and medical marijuana growth, quality and yield."​

Oregon medical marijuana patients, cultivators, doctors and advocates applauded the regulatory decision, citing their long-held concern that regulators were not looking at how hydroponics nutrients interact with medical marijuana.​

"Advanced Nutrients and the medical marijuana community give kudos to Oregon regulators for being the first state regulators to evaluate the science of medical marijuana and hydroponics nutrients," Straumietis says. "Our community is looking for similar action from regulators in other medical marijuana states."

It was big news. According to Advanced Nutrients they had scored an industry coup. US agricultural regulators were now working with arguably the shadiest company in the hydroponics industry to boost illicit crop yields or, at least this is what Advanced Nutrients would have you believe.

A Letter to Advanced Nutrients from The Oregon Department of Agriculture

NOTICE OF NONCOMPLIANCE
A recent Advanced Nutrients PR release titled, "Hydroponics Nutrients for Medical
Marijuana Gain Government Approval" (http://www.prnewswire.com/
news-releases/hydroponics-nutrients-for-medical-marijuana-gain-government-approval-95489084.html), with the company contact specified as Michael Straumietis, contains false and misleading claims concerning Advanced Nutrients products.
As I explained in a letter of February 23, 2010, to Advanced Nutrients, "labeling" means any printed or verbal representation used to promote the sale of any fertilizer,
agricultural mineral, agricultural amendment or lime product. Labeling includes, but is not limited to: sales presentations, brochures, posters, websites, printed advertisements, radio and television advertisements [ORS 633.311 (14)]. Press releases are a form of labeling.
Oregon statute [ORS 633.366(2)(a)] considers a product mislabeled if the label or
labeling is "false, misleading or deceptive." Using Webster's Third New International
Dictionary as a guide, a claim is misleading if it, "lead in a wrong direction or into a
mistaken action or belief." Further, in identifying "mislead" as a synonym to "deceive" the dictionary states that "mislead" "indicates a causing to fall into error of some sort,
intentionally or not." Products with labels or labeling using terms or claims that may
mislead a consumer are mislabeled, and prohibited under Oregon law.
1) This press release states, " .. . Oregon regulators have given first-ever official US approval to a brand of medical marijuana hydroponics nutrients ... "
The online version of the Merriam-Webster Dictionary defines approve as "to have or
express a favorable opinion of." Product registration means a product has met the
minimum requirements for sale or distribution in Oregon. No opinion, favorable or
otherwise, is expressed or implied. This statement, which applies to the entire
Advanced Nutrients brand, is false and misleading.
2) This press release states, " . . . Oregon regulators have given first-ever official US
approval to a brand of medical marijuana hydroponics nutrients ... " In fact, Oregon
has registered two Advanced Nutrients products with label claims stating the product
is for the production of medical marijuana. Individual products are registered for sale
or distribution , not brands. This claim, which applies to the entire Advanced Nutrients brand, is misleading.
3) The press release stated, "Until Straumietis asked regulators to evaluate the medical marijuana effectiveness and safety of Advanced Nutrients hydroponics formulas, regulators nationwide had apparently never considered how hydroponics nutrients specifically affect medical marijuana crops."
To date, Oregon has not received a request from Mr. Straumietis to "evaluate the
medical marijuana effectiveness and safety of Advanced Nutrients hydroponics
formulas .... " This labeling claim is false, and all "Advanced Nutrients hydroponic
formulas" may be considered mislabeled.
4) This press release stated, "Until Straumietis asked regulators to evaluate the medical marijuana effectiveness and safety of Advanced Nutrients hydroponics formulas , regulators nationwide had apparently never considered how hydroponics nutrients specifically affect medical marijuana crops."
This claim, that a state agency, which might be considered as an independent
evaluator, has evaluated and approved the safety of these products to produce
medical marijuana is false. This claim is also particularly disturbing, as it appears to be targeted to mislead a particularly vulnerable population, medical patients who have turned to medical marijuana in hope of some relief of their symptoms.
The claim that Oregon, the state referred to in the PR release, has evaluated the
effectiveness and safety of Advanced Nutrients hydroponics for use in the production of medical marijuana is false and misleading, and all "Advanced Nutrients hydroponic formulas" may be considered mislabeled…..

In Brief:​

Advanced Nutrients and the Oregon Department of Agriculture (the facts) ​

At present (October 2010) the ‘Oregon Department of Agriculture’ has issued Advanced Nutrients with five counts of stop sale violation, fifteen counts of selling unregistered products and eighteen counts of mislabeling. In addition, actions for sample deficiencies are in progress. ​

Prior to this, during the course of 2010 (Jan – Aug) Advanced Nutrients has been issued with numerous violation notices/penalties by the Oregon Department of Agriculture. ​

E.g. (Excerpts from FOIA material)
February 2010

“A recent review of advertising claims made by Advanced Nutrients in the
February 2010 issue of Rosebud: Hydroponic Growers' Lifestyle Magazine has
shown product claims that are inconsistent with the registered product label or
not compliant with Oregon Revised Statute (ORS) Chapter 633, Oregon's
fertilizer control law.
It is a violation of Oregon Revised Stature (ORS) 633.366(2)(d) to make claims in
product labeling that are inconsistent with the registered product label.”

Authorâ&#8364;&#8482;s note: Looking at the â&#8364;&#732;Results of Analysis â&#8364;&#8220; Heavy Metals (Big Bud)â&#8364;&#8482;, the HM (Heavy Metal) content found in Big Bud during independent tests is far higher than is stated by Advanced Nutrients. It is important to note that I make a recommendation in â&#8364;&#732;contaminants in cannabisâ&#8364;&#8482; (www.integralhydro.com/ advancednutrients), stating that Med dispensaries and/or growers should independently test fertilizers and not take manufacturer listings as fact. This is just one example of why I make this recommendation (there are many more). Further, the results of the HM tests indicate relatively contaminated synthetic fertilizers and/or organic components were used in production.​

Conclusion
What is clear is that Advanced Nutrients have no regard for consumer protection policies and regularly engage in misleading and deceptive marketing. In this case they have lowered the bar even further and utilized commercially depraved tactics in order to deceive consumers.
What is most worrying is that Advanced Nutrients have used two credible entities (PR Newswire and the Oregon Department of Agriculture) to support and amplify the deception. This form of parasitic marketing is likely to influence med growers, users and dispensaries re medical marijuana growing practices (something that Advanced Nutrients are all too aware of). One is also left wondering whether my earlier article (Hydro Hype 1) on Advanced Nutrients, their phosphorous myth, and â&#8364;&#732;Contaminants in Cannabisâ&#8364;&#8482;, published in Feb 2010 on www.integralhydro.com might not have inspired this latest outburst of grotesquely distorted marketing (I.e. parasitic marketing times three).
Further, as one Oregon Department of Agriculture representative put it â&#8364;&#339;This claim is also particularly disturbing, as it appears to be targeted to mislead a particularly vulnerable population, medical patients who have turned to medical marijuana in hope of some relief of their symptoms.â&#8364;

But Ben this is surely a step too far? Double the listed quantities of heavy metals (which cannabis readily uptakes like no other plant on Earth), deficiencies in the actual minerals listed on the bottle and lying about having a Government agencies approval?

That's surely just plain criminal, no?

I mean I knew they used "sexed-up" advertisements and pseudo-science to sell to unknowing growers but still.

It even states they make their products from contaminated materials...Advanced Nutrients state "only the purest ingredients...blah" on their website and no agency is going to make that statement lightly for risk of legal action.

They don't even make average nutes in that case (even if you buy all their range of bottles and potions) because at least other companies make their stuff from pure ingredients.

I even feel like starting a name and shame website for this shit.

UB, dont mean to hijack ur thread but after calculating my npk all together it comes out 23-12.4-36.2. Is this too high in K? im trying to get the yellowing and falling leaves to stop.

 

[Uncle Ben]

.....Why isn't this info plastered everywhere? The mentioned products are literally "loop-hole legal" poison in a bottle..

I bet 40% of their budgets go to attorneys, loophole scouts, marketers and graphic designers. The good Doctor covered how they beat the system:

"Snake oil products can sometimes be lawbreakers! Products that purport to control a pest such as a disease organism or an insect or weed, but are not registered with the State or Federal EPA and do not have pesticide
registration numbers, are not pesticides and can not be used for that purpose. It is a violation of state and federal laws to apply products as pesticides when they are not labeled for that use. Sometimes a product claims to boost plant health and thus avoid diseases, also avoiding the pesticide registration process. Health boosters, activators, and simulators are not considered pesticides by regulatory agencies; however, they are often not efficacious or supported by University research findings."

Bam!

Hmmmmmm, let's see......what have I heard about Canna? A little bit of personal history is in order. I and a few others (potroast for one) have been posting about growing pot for well over a decade, before high tech internet and modern websites were around. First there was ADPC, a newsgroup, and then a real forum came along called marihemp aka cannabis.com designed by a fella by the name of Ron. It was a site where all the heavy weights in this new industry congregated - Vic High, Brothers Grimm, Sensi, Greenman, me, Newbie aka Lucas, etc. Lot's of chatter, some noise but it worked....for a while. I modded 7 forums by myself. There were only a handful of seedbanks back then. One of the first Dutch pot companies to post to cannabis.com was Canna, and they were hawking a product that I found most disgusting, harmful. Was probably the start of what I suspected was the future direction for this biz. But I digress.....Canna's main spokesman (the owner) and I went toe to toe in threads regarding C02 tabs he offered which were supposed to do things for pot that would make you go bonkers.....all the typical flowery fluff, claims, and bullshit. Problem? C02 gas happens to be toxic to any plant's root system. Didn't matter what botanical thought I presented, he was going to say the sky was mauve and you better believe it's true. So, here he is pimping these high priced worthless tablets, noobs are eating it up (as dreamy noobs do) not giving a shit about the community and ignoring common sense botany.

I was using coir 30 years ago with orchids before it became fashionable in lala land.

There's another problem with most if not all "cannabis specific" nute ratios - they are too damn high in K compared with N. I really don't think any of them know or care about plant nutrition as some of this stuff is just way over the top regarding its design..... and of course they design in the need for additives and boosters by making their "base" products deficient in the first place. It's a racket.

This is a concept you need to learn well, nutrient antagonism --> http://www.totalgro.com/concepts.htm
An overage of K will impede the uptake of 3 of the most important elements for good cannabis nutrition - N, Ca, Mg.

UB

 

[Harrekin]

Ben with all due respect, one of their other pages states that some plants like a 1:2 ratio of N to K. http://www.totalgro.com/productprofiles.htm

Is there a nutrient profile for Cannabis that gives the perfect ratio required or is it guesswork on your part? Cos all plants have clearly different requirements (this is supported by the link above).

Thank you.

Get rid of everything but the Fish Emulsion and watch them get green...and at least 1 tablespoon(15ml)per gal of water. You could probably go 2 tablespoons per gallon feeding them once or twice a week......

If those are Advanced Nutrient products you can't reliably add up what the NPK is, because they lie on the labels.

High K levels are fine, it's the Phosphorus that's retarded in all these companies' products. I mean who ever gets K toxicity/antagonism, wtf. I've seen many people fry their plants with a P/K booster, but it's the phosphorus and manganese/zinc lockouts.


A+B Canna aqua is a fine standalone product. No additives other than acid/hydroxide, obviously.

Thank you.

Of course. You surely would not give cacti a high N food. You'd probably kill it. If you noticed, most of the foods targeted for foliage production are high in N. I treat cannabis as a flowering foliage plant and in its natural environment it gets more N than anything else so for me a 3-1-2 works.

Years ago Canna was pimping them. Now it's No Mercy which may be a spin off of Canna. https://www.nomercysupply.nl/en/framesets/fs-prod-co2tab.html Hype includes the emotionally driven drill of "plus it's environmentally friendly!"

High levels of any one element is NOT fine, and that certainly includes K.
