Not "TMV", which, fun fact, "was the first virus ever to be discovered" and affects the Solanaceae family and not the Cannabaceae family.

But... thanks for pointing out Sunn-hemp mosaic virus, +rep :clap:

Thank you thats awesome :)

Depending on what you read you will find it called by different names, but it's kinda like herpes no matter what type or what you call its still the herps :shock::lol:

Yeah I agree, you seem to be correct. SHMV can be considered just another hemp specific form of TMV.

Again: :clap:

Thanks again lol

I live in a state that has good weather for tomatoes, tobacco, and cannabis. I grow different varieties of tomatoes in my garden with my meds and I researched to make sure they would be good for "companion gardening".

so because of this, i just read (actually started typing this last night and just came back to it) the first and last page of a TMV: Cannabis thread on icmag... (might as well start calling it "CMV," even though there's already a "cucumber mosaic virus") ...and now i'm worried. Some are essentially suggesting that "TMV" becomes congenital, in that an infected plant will produce infected seed... which has allegedly affected some well known mass produced strains, resulting in those strains/genes being "congenitally affected." (in other words: if you bring those genes into your environment, you'll permanently taint your environment w/ TMV...) ...What??? Say it ain't so!

(i've now learned that this would be called "SHMV")

Why does this worry you? Do you suspect you have an mv? For all I know most or even all of our common cannabis gene pool isn't even susceptible for it...

A bit more research shows that sunn hemp is not as close to hemp and our mj cannabis as the name suggests: http://en.wikipedia.org/wiki/Crotalaria_juncea It is in fact a different family: Fabaceae

The wiki page that says what I posted above: "
Effects[edit]
The hemp mosaic virus infects plants of the Cannabis genus. The virus causes cellular mutations, stunted growth, damages plantsphotosynthesis ability, and more. Cellular mutations usually manifest as discoloration and misshapen leaves. Discoloration usually manifests as yellow or grey mottling that can form a spotted, mosaic, or streak pattern. Misshapen leaves can be the result of damage to the plants at a cellular level, making them appear contorted and/or twisted. The stunted growth can cause a tremendous amount of crop loss due to lower than normal yields. Loses of 25% of flower production or more have been widely observed and reported.
"

has zero citations and could just be flat out an error...

A not-so-thorough search shows all sources that link SHMV to cannabis, besides that wikipage and Ed Rosenthal's book, are mj grow sites... Is Ed the source of the myth...

The other wiki page: http://en.wikipedia.org/wiki/List_of_hemp_diseases is despite its title not talking about SHMV in the context of our type of hemp (cannabis sativa) either.

Was that about ChemD? It was suspected that strain had it, several have tested their clones (apparently there's a kit to do so yourself) and it tested negative.

While it seems plausible that one of the many different mosaic viruses "could" infect cannabis... I have yet to find a confirmed case and at this point it seems highly unlikely there even is one.

The mere plausibility that such a thing could happen (and may already be happening without scientific confirmation), is enough for concern, IMO.

I saw the list of various types of plants the 3 types of Tobamovirus can affect, and the idea that it "should be considered airborne" (due to infection spreading by as little as contact from a mobile pest), is a bit disturbing.

I then began to ruminate about how, in this justifiable-germophobia of modern times (i suppose that's an oxymoron), i've managed to reach my current age, without ever even having heard of TMV (until yesterday), or ever having known that it was "the first virus discovered." It seems like with all these scary viruses all over the world, "the first virus discovered" would be an important history lesson... (especially since the 3 types of it combine to potentially affect so many different kinds of plants)

Meanwhile, at least a few of those potentially affected plant types exist in my immediate vicinity, and since it spreads via contact (often invisible pest contact, at that), it "feels" a bit worrisome. Now i'll be paranoid and keep an eye out for symptoms (kinda like a hypochondriac, but with plants). The prospect of finding myself in the position of struggling with an as-yet-unconfirmed affliction that scientists aren't ready to "officially acknowledge/confirm," is not so appealing.

But i'm definitely not saying "the sky is falling!"


And then i saw that "RNA Pro" product, designed to allegedly protect the RNA of infected plants... $300 for 8 oz! lol. That's plant-meds i won't be able to afford. ^^

you know that illness sounds like a bad grow from one who is learning lol. I have not heard of it being verified but now i know its out there.

It does look much like TMV or perhaps another species of mosaic virus. I didnt read the whole thread so sorry if im repeating what someone else said.
I'd seperate it from the other plants, dont use the same pruning tools on it and your other plants unless you disinfect in between cuts.
I didnt think your plant was really badly infected either. just finish the grow and move on....with diseases its all about prevention rather than treatment especially on food crops or crops used for medicinal value.

Oh, I hate to post this after Snaps has posted (no relationship in my answer to you posting Snaps) as I have answered on this MV issue before with Snaps answering before I did.

I do NOT believe that it's a MV of any type!
Sunn-Hemp is a tillage ground cover crop for farming! It is NOT a Cannabis related plant! Just because a plant name has "hemp" in it. Sure doesn't mean it's related!
With that said, Wiki is a user supplied information source web-i-pedia. Just who supplied the info that it (sunn-Hemp MV) infects Cannabis? The same for ICM or any related Cannabis grow site !

I am in a little "collective" of LONG time growers. We have sent HUNDREDS of samples to Mich. State University Ag. science for testing, looking for MV infections. NONE have EVER come back as positive!!!!!!
I have spoken directly to a Professor there that deals with nothing but plant disease/pest problems. He has not seen an infected (MV) cannabis plant ever.
With that said. I asked if it's possible that Canna can be infected. He was not "sure", but felt it was POSSIBLE. But he had some other points on the subject.
He felt that if it was a problem it was during the years of commercial HEMP production and he stated that he had NOT seen writings on the subject to indicate any large scale problem on record. He felt that it MAY be being bread out of our plant with the breeding being done in relation to it's use!

The visible "infection" would spread through out the whole plant and show it. ( I have seen here, one picture of a plant, that I SURE would have had tested. Just to know if it WAS an MV). The results would be to severely reduce the growth and yield of the plant.

Broad mite infection CAN appear like a MV infection. The difference being that it will not spread about the plant or transfer to others very fast. Broad mites are VERY small and attack stems and veins of leaves by digging in a bit and that damage creates the "curve" and the "mottled" look by limiting nutrition to the "down stream" effected area.

MV is transmitted by Bug bites(giving a wound location for infection) or by physical TOUCH from infected plants and Humans that have touched infected plants and then touching healthy plants.

I feel that may be possible and I would LOVE to see if it's real by a positive test if it is! (Don't wish that on anyone though).

With that said, I don't BELIEVE I ever will as it's not been proven to have happened around here, or anywhere else I have been in contact with, YET!

Treat for Broad mites with Forbid 4F.

IF and I do mean "IF", it gets worse and begins to spread out the whole or a major portion of the plant. Get it tested if you like. A handful of single leaf infection area's DON'T count!

To perpetuate the MV "myth" is wrong. I hope I supplied real world intel on this subject and hope you all learned something to use to your advantage.

If you believe in MV and believe you have an infected plant. Isolate it and don't touch it before you touch other plants in your grow. Sanitize your hands after touching what you "believe" to be an infected plant with an alcohol based hand sanitizer before doing ANYTHING else in the grow.

I don't care what size filter you have on your intake OP. Infestations are not an "if", they are a "when". Too many ways for pests to get in besides air intakes. Besides, BM's are TINY, around the size of a White fly leg (you saw the above picture right?). They can go through many intake filters.

Again, I hope everyone learned something and uses the knowledge for good.

Thanks for everything guys and gals. I've never taken several peaces of advice. First, I added rocks to the bottom of a pot, and set the plant in question inside of it. Giving the roots better drainage. I once again spent the morning scouring the plant for and type of bug , mite, egg... nothing. So i'm going to foiler spray with forbid 4. Just in case.
On a totally new type of diagnosis, could it be a heat and humidity issue? My temPs are usually 85-90°f but humidity is never over 35. I found these pics and articles on another site. Looks similar to my issue. Would appreciate your guys expert opinion on weather this is b.s. or not. Theas are not my plants or my advice. It came from a random weed site.

absolutely, funny how the obvious isn't always so obvious when the internet clogs it up with bullshit.

Your link doesn't present all the looks of broad mite damage so may not be convincing. It can often present with the curled leaves so op should google for more pics of damage.

Here are more pics off the internet on mosaic virus in cannabis. The first 3. The 4th 5th and 6th are my Pineapple Chunk i'm, not saying it is or isn't. I'm going with the rocks 4 better drainage first and well go from there. Ill post picks and keep it updated. Also fella who said I could send a sample for testing somewhere, where do I send it. Thanks again to all. Love light prospairity and abundance be yours.

And chuck has echoed again the point that what you find on the internet can be suspect at best.
Who posted what, at what site and how did they confirm the problem as being what they posted it under?

Call any local college in your area that has Agricultural Science classes. I suggest you call first and find a professor or Grad student that will be willing to test your sample. You can simply send a small sample that would be hard to identify as to what it is. But remember that these are experts in the field and being up front about what it is and why your testing is much more likely to get the response you want!

Every State has colleges that teach Agriculture.

P.S. (edit) I can assure you that is not a heat stress problem. Although from your last post I do highly suggest you lower your grow area temps to below 81 F for optimum results!
Cannabis at 90 F almost goes completely dormant due to it using it's available "energy" to keep it cool. "Translation"; The plant is using almost ALL it's "energy" to stay cool enough to survive the "heat wave". When it does this. How much "energy" is left to use for actual growth?
