Mosaic Virus in Cannabis pics

[BlueGrassToker]

I would bet big money that that is NOT a virus, and for sure not TMV.

No disrespect intended, but so many in this thread are giving warnings about things that they only think, and none of what they actually know.

TMV is a mother fucker folks. If you have it, there will be no question that you have hell unleashed on your crops...ALL of them. If TMV exists you can be certain that it will eradicate your entire crop.

I have not seen one example in this thread that looks like TMV whatsoever.

(shrug) I am not going to argue with anyone about this...but if someone Knows they have TMV, then get a test and show us. I haven't seen any takers on that yet.

BTW....nothing is going to "grow out" of TMV. No how, no way.

Aspirin? Please....
Listen to MIway.

Well, if that's the case, why not show us some photos of real TMV in cannabis?
And also, explain how you know that it's TMV, and why the OP and others are wrong about TMV.
While I agree that many photos posted here are not TMV, I do believe that some of them are. I also believe from what I have read that some plants do grow out of it, and that certain strains, namely Blueberry, often have it but that it has no lasting negative impact. Please enlighten us if you know better. No sarcasm intended, as I would really like to know what mystery disease destroyed my grow space. Never thought it was TMV because of the difference from the photos of alleged TMV here and on other sites. But maybe it was. We are all here to learn, and I am not looking for an argument, so please enlighten us with some evidence. That is a sincere request.

Actually, he who asserts must back up his claim.
I have never seen TMV in cannabis, although I have seen it in a tobacco crop. Trust me, it is not something you can just water your way out of....

Hell I am no horticultural expert, I have only grown pot clandestinely for years. I have experienced just about everything shown in this thread, and it will always boil down to having something out of whack. It only takes an overage of this or that, or a shortage of that or this, and what we are being shown will materialize. Just having the pH off can set plants into turmoil.

Media with a bit too high count of anaerobic bacteria can also set plants into a tizzy.

Even benign coco can cause plants to go south...especially if the excess salts weren't washed out of it. (don't ever trust coco without washing it out)

I have never seen TMV in cannabis,

That pretty much sums it up.
If you have never seen it, you don't know what it looks like.

So based on suggestions here I put my potentially diseased girls back in the cab along with a watering featuring 325 mg aspirin.

 

[RetroGrow]

What are your options?
Can you easily start over with new clones?
Without them being infected too?
I would try to grow them out, but it depends on your situation. As long as they are growing, it shouldn't matter if some of the leaves are twisted.

 

[Canniwhatsis]

Variegation seems pretty commonplace with many of the newer strains, In house and garden plants it's actually sought after! I actually just grabbed some pepper pods that should give me mottled leaves to grow as decorative peppers next summer!

One of my DJ TrueBlueberry's has some spotty patterning on her leaves, but she's the more stable, heavier yielding, and more potent of the 2 pheno's I got! So certainly her mottling isn't due to a virus.

These were C99 F1's from seed. Honestly, after that treatment, they all look 100% better. even the slightly wilted ones have perked up.

BTW, it did not originate from the seed, but from me some how.

Are you talking about the aspirin?

 

[funkervogt]

Are you talking about the aspirin?

Yep.

 

[funkervogt]

BTW, HOW COME NOBODY HAS COMMENTED ON HOW AMAZING THIS IS?

both plants same age, same strain, same food, same everything except the larger one gets 325mg/gal of asprin added to her meals.
the taller one was repotted into a larger container a week ago.
it seems to me that asprin does help controll the symptoms of the virus.
notice the leaves and branches falling off of the little one, it has no hope for yeilding anything!

Bro, you are preaching to the choir. I've been using aspirin for years, and it truly is a miracle drug for plants. If you have plants with any kind of sickness or weakness from insect attacks, aspirin will boost the plants natural immune system and the results are often dramatic. You can see the difference overnight.
An improvement after treatment pretty much confirms your plants are sick, but you can take them to harvest by continuing the treatment with each watering/feeding.
The downside is, any cuts will still be infected, so taking clones just keeps you in this perpetual cycle of having to deal with sick plants. I finally gave up after two years of trying to fight an unknown malady, but it didn't prevent me from harvesting thanks to the aspirin. Constantly having to grow from new seeds is a pain in the ass, and you never get to select that special plant because it is still sick, even if not symptomatic. Getting a virus out of your environment is extremely difficult, however, viruses can't survive temperatures of 140 degrees. Outdoors, farmers use plastic sheeting over their plants. As the sun penetrates, it heats up under the plastic and when it gets to 140 degrees, the virii are killed. I don't know how I could get my inside environment to that temperature, but that's what it takes to kill a virus.

A sample size of one may be enough to convince people reading this thread, but mathematically, its insignificant. The sample size is very small, and the results can't easily be attributed to the aspirin.

The plant in the dixie cup looks overwatered. Droopy leaves and water stress induced N deficiency. Even the soil is clearly saturated, while the plant in the one gallon container has dryer soil.

I would love to see a picture of the dixie cup plants rootball. That will tell the whole story more than anything else.

Instead of everyone jumping to the virus conclusion, they should get their fertilizer solution, tap water, and media tested when they are having these type of problems. Maybe look into getting tissue analysis done if possible. Doing anything less is an injustice to your garden. Find the more likely culprit. Dont just assume its a virus.

Retro, from what you have shown and described, you haven't seen TMV in cannabis either.
For one thing, nothing will grow out of TMV. You seem to assert that it does. (shrug)

How do you know this if you don't know what it looks like?
How do you know nothing will grow out of it?
It is not my assertion. I got it from my reading, from others who have reported it. You are making a statement that nothing will "grow out of it", yet, by your own admission you have never seen it.
I don't know how you can be so certain about something that you have never seen or experienced. Where are you getting your information from?
You seem to have formed an opinion based on nothing. You have no facts or pictures to back up what you are alleging.

 

[BlueGrassToker]

i stated i have seen tmv...in tobacco. tell me you arent basing your knowledge on this topic from this thread...cause this thread is chock full of misinformation.

 

[funkervogt]

Here's my question: where else do we see Variegation and warped leaves of this kind in any other plant problems? I don't recall seeing either of these symptoms in part or all due to a micro nute deficiencies, nutrient lockouts, Ph problems, etc.

 

[the gnome]

here's a pic from the 1st page/post #7 of this thread of a plant supposedly having TMV

and compare this to the pic of mine

i got a test kit for $27 and tested my grow and it came back negative.
NOW!... another member here said his plants looked the same way after a severe nute lock out, exactly like it.
I also found a pic on yahoo search for hemp streak virus that show a pic just like the two Im posting here???


there's a lot of misinformation in this thread.
Ive yet to really see a definitive pic of a pot plant infested with TMV or hempstreak virus.
but I don't even know what it looks like either because I can't definitively find a pic of it!
does anyone really have a plant thats infected and tested it out positive and taken a pic???????
I think 99% of the cases in this thread are really due to other probs

 

[funkervogt]

What about leaves like the one on the left, 2nd finger from the right?

There really is a disease of cannabis, the hemp streak virus, that is probably more common, and also closer to the symptoms many have shown:

"Viruses
Viruses rarely kill Cannabis. They only exist and replicate in living plants. Viruses can, however, seriously reduce yields. Once acquired, they are nearly impossible to eradicate. Viruses invade all parts of plants. Pollen and seed infections transmit viruses to subsequent generations.
Five viral syndromes are described in the literature. In addition to these naturally-occurring infections, Hartowicz et al. (1971) screened 22 common plant viruses for their ability to infect wild hemp. Over half the viruses could infect Cannabis.
The hemp streak virus (HSV) is frequently cited on fiber cultivars in Europe. Foliar symptoms begin as a pale green chlorosis. Chlorotic areas soon develop into a series of interveinal yellow streaks or chevron-stripes. Some-times brown necrotic flecks appear, each fleck surrounded by a pale green halo. Flecks appear along the margins and tips of older leaves and often coalesce. Streak symptoms predominate in moist weather, flecks appear during dry weather. Leaf margins become wrinkled and leaf tips roll upward, leaflets curl into spirals. Whole plants assume a "wavy wilt" appearance.
The hemp mozaic virus has been described on fiber cultivars in Europe and drug cultivars in Pakistan. Symptoms were described as a gray leaf mosaics. Three other viruses have been cited on European hemp—the alfalfa mozaic virus (=lucerne mozaic virus), cucumber mozaic virus, and the arabis mozaic virus. Many insects transmit these viruses as they feed from plant to plant. According to Ceapoiu (1958), the worst vectors of Cannabis viruses are bhang aphids (Phorodon cannabis), greenhouse whiteflies (Trialeudodes vaporariorum), onion thrips (Thrips tabaci) and green peach aphids (Myzus persicae)."

Wikopedia has this list of viruses that attack cannabis:


Viral diseases
Alfalfa mosaic & Lucerne mosaic genus Alfamovirus, Alfalfa mosaic virus (AMV)
Arabis mosaic genus Nepovirus, Arabis mosaic virus (ArMV)
Cucumber mosaic genus Cucumovirus, Cucumber mosaic virus (CMV)
Hemp mosaic genus ?, Hemp mosaic virus
Hemp streak genus ?, Hemp streak virus

A common viral disease that affects cannabis is Cucumber mosaic virus:
"Symptoms seen with ths virus include leaf mosaic or mottling (Fig. 2a), yellowing (Fig. 3a), ringspots (Fig. 4a), stunting, and leaf[13], flower and fruit distortion."
