    This hurts us all and we're all feeling for you. A total shame. Only thing to do is start over and after cleaning and disinfecting hope it's taken care of. Total loss total shame.

    Jordann if I didn't have clones cut from the same mothers running at another facility in perfect health I'd be inclined to think that was possible - but it also affected plants from about 14 different strains. I also changed up nutrients, fed quarantined batches of what appeared to be healthy plants an entirely different mixture, and a few other things that rule out a bad batch of food or medium.

    Rwise root masses are EXTREMELY healthy. Very dense, properly formed, nice and white. I've examined plant material, root material, and growing medium under a bona fide microscope. There is absolutely zero indication of any kind of insect or pest vector.

    Looks like a mix between pot and tomato...

    Good God, I am literally sick to my stomach. This has been by far the worst thing I've ever experienced as a cannabis grower.

    Since my first post in this thread, whatever viral vector infected my plants spread like wildfire, no matter what I tried. Plants that were perfectly healthy one day were clawing and going yellow just a few hours later. I've sought help from everyone available, including the local extension office - who said they would not touch or advise on ​​​​​cannabis.

    I still have no discrete answer in terms of what virus (or even if it is a virus) infected this grow, how it started, what the transmission vectors are, or what any possible effective treatment would have been.

    I had to make the awful decision today to burn everything and start over. I just filled up an 8 cubic yard dumpster with about 2,500 plants that were almost all perfectly healthy just a week ago.

    I first noticed these symptoms in a few plants about 6 weeks ago. At the time I didn't think much of it. Anyone who has grown large quantities of cannabis knows that sometimes you get a few plants that just have weird growth patterns. That's what this seemed like to me at first, and for the first week or two I tried to nurse those effected plants along. So a word to the wise: if you have something you don't know what it is, chuck the plant.

    Once I realized that whatever it is was spreading, I spent another week attempting a cure (see elsewhere in this thread for the range of things I tried.)

    Perhaps if I had just jumped directly to triage once I identified that it was spreading I could have saved a bunch of them. At this point I'll never know.

    Things progressed very slowly up until a week ago, and I had plants that mostly all looked healthy. I had quarantined those affected and started to dispose of them, but about a week ago everything went to hell.

    It's kind of surreal having to do what amounts to a mass grave due to viral infection while the entire world is simultaneously dealing with a viral pandemic of its own.

    I did not read all comments but upon 1st glance they reminded me of some tomato plants I grew in black plastic pots where the soil was too hot(rich) and the soil also got baked in hot temps resulting in twisted growth of some of the branches and leaves.
    I had to repot in amended/blended soil and protected the pots in shade to help the tomatoes recover somewhat.

    Yes. Update update please. Pics too if you're not too busy. We're all following this thread.

    Maybe some fertilizer that turned to shit with time or something

    I am new to clones myself, and I do see some odd things with clones that I dont see on plants from seed. If it were the genetics it would be most or all of them. (IMHO)

    Clone genetics go to shit?

    I see the same white and light green spots on both, some claws also. (this is what makes me think bugs) I will take it they were about the same size when potted. The little girl is definitely unhappy, when you inspected the roots, was the mass as large as it should be? (for her age) Also have you used something like Voodoo Juice to help root growth? Foliar feeding anything? I am running out of ideas for it to be something other than a viral, or intentional thing.

    Shit 😔 I mix my own out of 6 different varieties and once I mixed improperly when amending with nutrients back in the day. Some got really high levels of ferts and did what yours are doing and others were completely unaffected.

    Viruses can be detected but I believe it would require an RNA analysis similar to those being done to detect the Corona virus. I understand the lockdown of testing facilities at this time may put a damper on that plan for now. As far as agriculture is concerned, certain viruses can be deduced from observations of the plant’s growth changes, discoloration, lack of fruit production, etc. For example the tobacco mosaic virus when it attacks tomato plants creates an unmistakeable mosaic “look” in the infected plant. No treatment for that is recommended except removing the infected tomato plants from the rest of the good plants and destroying them to prevent the virus from spreading.

    Rwise here's two in a side-by-side comparison. Same mom. Same coco. Same environment. Same feeding schedule and amounts. Same age.
