Damn there should be a warning to everyone to read through this entire thread before making any harsh decisions! I was almost in tears as I read the 1st few pages thinking I was fucked!

Any idea as to how your grow initially acquired this problem?
Any ideas as to how it spread? ... Shared reservoirs? Insects? Plants touching?

I picked up about 20 clones (different strains) from various clubs in SoCal. I first noticed the problem on two of the new clones after about 3 weeks of veg. I assume one of the new strains was infected with the virus, since I had been running the same 3-4 strains for 2+ years prior.
I handwatered the 20 clones in keg cups of coco for the 1st 10-14 days I had them. Then I transplanted them into hydroton on an ebb and flow table. 10-14 days later I noticed funky new growth on 2 of the strains. They shared a reservoir after being transplanted and their leaves did touch most of the time I had them. I never had what I would consider an 'infestation', but there were always 'some' fungus gnats around too.
I figured I'd make my contribution and throw my 2 cents in here.
Ive been growing for the better part of eight years and have been hit with TMV (or similar) twice. The first time I was a new grower and had just returned from a trip to the Caribbean where I smuggled back some cuban cigars. I unwittingly used to work in my garden after smoking these cigars. A few weeks later, I started to get twisted and blistered leafs. I witnessed it spread from one plant to another before I finally figured out what had happened. I scrapped the grow, sterilized and did have not mixed tobacco and growing in any respect since.
About six months ago, I had a stable of 4 or 5 mother plants. I picked up a Flo clone from a local dispensary. I vaguely remember seeing some tobacco products behind the counter and thought it was a bad idea for a store selling clones to have employees that smoked. The Flo clone would show viral signs any time she was stressed in veg, but I thought it was normal since it was a blueberry related plant. I started to see signs of mosaic virus in other plants in the mother stable, but these were chem and og related strains so I still did not think much of it.
Around this time, I started to flower a batch of green crack clones from the same veg area. Everything was fine until the second week when the new flowers were hairless like those hairless cats. Upon a closer look, the hairs were black and stopped coming out once the tips were out. I started this thread http://www.icmag.com/ic/showthread.php?t=193113 not knowing what the problem was. I got lucky and these girls snapped out of it after three weeks and I netted a great harvest of some proper gc.
Fast forward to my current grow: A SCROG with Wifi OG and Chem D in the same setup, only SCROG. Im currently 3.5 weeks and don't appear to be as lucky this time around. I had the same problems with flower development. Three weeks in they started to shoot out some normal pistols, but still about half the sites are nubbed and hairless with leafs around the bud sites deformed. Other than that, they could not be healthier.
So, based on my experience, here is what I know about this virus, whatever it is:
- Definitely provoked by stress. All these plants were very vigorous and healthy until they started producing flowers. It seems like simply flipping the switch to 12/12 is all it takes. Photoperiod changes trigger the virus.
- Another interesting observation is that both times, the one plant nearest the intake had the healthiest flowers, by far. The further away from the intake, the less healthy the flowers. I recently upgraded the exhaust to a great inline whisper fan, so circulation should not be a problem, but things do not appear any better since even though temps are down.
- The bud sites closest to the light are in the worst shape. Temps here are in the low 80s, so heat should not be an issue. Apparently the virus does not like intense light.
I also believe that using a screen or trellis on my current grow has caused more stress. It also sucks because I cant move the plants around.

Seems like the relevant question, especially for people in SoCal, is wether the correct approach is to avoid plants with the virus or get good at growing plants with the virus. If most the OGs and Chemd are in fact infected, seems like you're better off accepting it and working around it.
What do you guys think?
What do you guys think?
if all the OG's and Chem's are infected with it, how come there is still so many growers pumping out amazing flowers of the stuff? its not like it just randomly decided to pop up in someones garden.
Because the virus is triggered by stress. If your environment is dialed in and your plants are stress free, it's very likely that the virus will remain dormant or not be a major issue.

This is reeking havoc in NorCal too! I am currently clearing out multiple rooms and scrubbing the hell out of all equipment, pots, etc. with Physan 20. The bitch about this is that so many people here have it and don't even realize it. Irresponsible growers have been growing with it for a while and don't know what they're up against. They continue to grow, take cuts, and pass on this horrible virus, without even knowing what or the extent of what they are propagating. From my personal experience, this is reaching a critical level. I recently saw a flower room that was 70-80% infected. It will almost be a total crop loss for the grower, as I don't even see how he will be able to move the product.
I have had this surface in 3 separate scenes within the last couple months, after never having any issues from it in my previous 10 years of growing experience. I am on a fucking warpath now! Plants look great, until 2-3 weeks of flower, then the tops fried. Eventually they grow out, after 2 weeks of zero bud growth from the fried buds. THIS IS ABSOLUTELY UNACCEPTABLE. This has become the worst pathogen that I can remember coming up against. I will no longer accept any plants from other growers, as I believe that I was infected via a buddies cuts. Once my scenes are quarantined, I will only start new varieties from seed from reputable breeders.
Has anyone had success with eradicating this virus from infected plants? I currently have a sizable amount of vegetative plants that are being prepped to disperse to numerous spaces to flower. My concern is that a percentage of the plants are infected. I refuse to let this issue progress any further. Let's figure out how to keep this nasty virus from decimating cannabis crops!

highbrid1, on my last harvest, before scrapping all my plants and starting over, 1/3rd of the plants also put out shriveled, dark pistils in early flower. They also pulled out of it within a couple of weeks, and ended up producing dank.
You may be right about stress. All my stuff looked beautiful until I used some bad (dark, cloudy) calmag. Maybe that was enough to trigger the virus? I don't know if it was definitely the bad calmag that made the virus explode, or a coincidence, but the timing is about right. Or maybe the virus was about to explode anyway.
Either way, I did a serious deep cleaning and started from scratch. I'm 2+ weeks into veg with my new plants and everything looks good. After 2+ months of chasing the problem, it is awesome to see new, healthy growth again.

any one know what this could be only 2 cuts showing this out of about 35 in seedling compost just rooted only had ph'd water and 6 inch away from my 125w cfl they were alright last night woke up and they were like this
Yeah it does seem like its just a matter of time before mosaic viruses are in ALL cannabis plants and it is getting to the point of being a very serious problem. The reason is so many people grow nowadays that it's spreading rapidly. Most these people are uneducated and/or dont care.
Of course, stress weakens the immune system and gives pathogens and other problems a window of opportunity. It's the same as viruses in humans.

Dude, get some perlite in that medium. Thats no virus. Lack of oxygen in the root zone fasho.

dont think its that pal i have over 30 other cuts in the same medium not showing any problems and i aint used perlite in years never saw any benefits when using it
Ive seen several grow rooms affected with this virus over the past couple of years. I continually scratched my head about the symptoms. I thought it was the ph, nutes, water, plants, etc...After reading this thread I think what it's the TMV or something that's closely related to it. The question is, HOW DO WE GET RID OF THIS SHIT!!!! I've seen several grows start out healthy, then 3-4 weeks into flower you see the leaves wilting, brown tips, discoloration on leaves, etc...Then the whole thing gets krinkly, and dies or looks like so much of a shit pile that you have to destroy it. If anyone has used anything to kill this virus or even control it, please chime in....
I'd rather deal with mites & thrips at the same time, then deal with this shit...lol
MJ God please help us

TMV is so rare, most with root disease or overferting, poor environment who blame a disease for their ignorance. I have seen plants with TMV and the discoloration iV completely different. That looks like a sulfur or zinc, molybdenum defic. 1 lateral side of the leaf will lose color where the other side is green as cqn be. I been doing this a long time and my friends n I have only seen the virus a couple times. I'm running alien dawg, sour d, apothacary chem '91, some of my own og crosses and I can you none of them have TMV. They have toohighmf disease.. poorly fed, no meter, tap water, excessively hot, warm stagnant res but everything is good and ready to flip. Thanks to clorox, and oxygenation.

i have been growing the same strain
i have been growing the same strain
for a while now, and it definetly has tmv.. but if you dont stress the plants only now and then youll spot a hookleaf or discolouration spots and then as you watch it progress to loose of greenness and then to where it looks like a caterpillar ate holes or edges off your leaves..
the extra protein deposits in the leaf burn and decay..
my plants are still vigous and harvest quality and quantity..
ill get closeup shots of different stages and ill throw them up to help spot and identify TMV..
i have not noticd dryed out plant matter, it seems to disappear or degrade, not shrivel up and dry out..

They dont have tmv, if they did they would infect other plants and they dont..
