There are thricomes on the new buds, but not much smell, it is still early though, even the "normal" plant has very little smell. It seems the blighty plants are flowering more slowly than the "normal" plant? But it could just be all the black surrounding the buds that make it appear that way. I dont think it is a mould, it doesnt come off, in fact it almost feels a bit brittle and dry. n This is a branch I cut off and then cut a baby bud in the bottom.

Something in me says hell no nope not gonna smoke that. I have the same purple on my plants out front.

That was probably the branch with the worst amount of "black blight", so I may get something off of other parts and plants? Not sure if I should clip off everything that looks really bad or wait it out and see what happens for experimentation purposes.

It is no big deal if I get nothing from those plants. I have plenty of jars in the basement and I already harvested my autoflower plants this year.

this is what mine looks like and it's spreading. The normally don't fade like this. This is a purple nonsulfur bacteria of some sort 😳 I know in the soil it's good.

Here are pictures from today. It is like the 3 Blighty plants are budding earlier. They have orange pistils, but not the normal looking orange. I get the feeling I may not get very much/anything from the 3 blighty plants? I am going to cut open a bud later and see what it looks like inside. They look to me like mouldy buds, but i dont think that is the issue. The first picture is a "non blighty" plant. All the same seeds, first plant is about 10Meters away from the other plants

Yeah, that stuff kills it! May take a while because the plants are pretty big. Lucky It didn’t get vectored over to your good plants.

99%, it is a Phytoplasma, and is mainly transmitted by Leafhoppers, and other biting/sucking type insects.
THERE IS NO CURE.

It, is extremely contagious., and dont touch any other plats, after you have come into contact with said plant(s).

Sometimes they grow out if, most often, in my experience, is that they dont.

Weve been battling it, in NE Ky, for more than 14 years.
We have been growing weed here, since at least 1972, and this shit just popped up, around 2012, and has caused damage, every year since. Sometimes taking 80%-90%, of the crop. We have Literally, lost more than 1000 plants to this, in 14 years.
It generally crops up, right before they start to flower, and it mostly starts, on the growing tips.

Also, a couple people, have mentioned Witches Broom, which it MAY BE, BUT, Ive never seen one photo posted, by an authority, that says it is WB, and Ive NEVER seen any photos of WB, being purple. Ive seen all kinds of fucked up. But, No Purple.

Id bet, $1000, it IS some type of Phytoplasma.

Duke Diamond VA-Dominion Seed Company- told me of a place that may be able to test for it, in Colorado, and is who he uses.

This is from this site, and there are others

Dark Purple Disease Affecting New Growth?​

phytoplasma#chapters-articles This mentions the aster yellows on carrots misidentified as witches broom. Also, there are 3 type of insects that cause this, not just the leafhopper, like I stated above.

I just Emailed a lab, in Colorado, and asked them, if they can test for Phytoplasmas.

I’ve had several plants go bad like these. Learned from experience that as soon as you see this issue and no matter how old the plant is, chop and keep healthy ones healthy. It’s not worth the nutrients, time, and worrying for a plant with low probability of maturing. Hope your other plants do well.

what are your temps at night?
1st thought is cold temps at night bring out the anthocyanins but that 1 leaf looks weird to me.
someone better will reply i'm sure

Its not caused by:
Cold
ANY type of Nutrient Deficiency
PH
Soil/Medium
anthocyanin
Its been 90f 100f-where we are, and 72f - 75f, at night, and it started 1st week-, of August. As it always has, for the last 14 years. Sometimes, it starts, in late July.
Same plants/Clones, Inside, in the same Medium, have never one time, turned purple. Ever. Since 1977.
And it doesnt discriminate vs well known seed company genetics.
Out of probably 20+ different seed companies, all of them have at one time or another, suffered contamination, but like I said, they never do it inside.
Ive also read, that if seeds survive, to be germinated, Phytoplasma, is transferrable, to the seeds.

I remember a thread on this from 4 or 5 years ago when it was just starting to come around and you were instrumental in identifying this back then, and I remember it as well.

YEP. Its a fucking plague.

Only way to really control it, would be to nuke the whole area, far beyond the grow area, and keep nuking it on a regular basis.
Not to mention, nuking the plants.
And thats both unhealthy for everyone./All living things, irresponsible, and not feasible.

The 1st Phytoplasmas, in Marijuana, was observed, in 1967, in Iran.
The 1st Phytoplasma EVER discovered was also in Iran, in 1965, in Sesame Seeds.
It was predicted, to spread worldwide.

While my assumptions, are only guesses, I believe what we are seeing in weed, also affects Potatoes, and is called.
Purple Top. While only guessing.
It seems curious that there is a known phytoplasma, in potatoes, that causes purple top, and considering that weed, starts purpling, from the growing tips, its not a far jump to assume, that this is

Phytoplasma known as 16SrXII.

I have no idea, if it has ever been identified in weed. If it has, Ive never heard of it.

On this list, it looks like there are 3 different plants listed, that are affected by the Phytoplasma known as

16SrXII.

In the Alfalfa, it causes Yellowing

In Potatoes-PURPLE TOP.

Yup, I remember it, here's the old thread.

OP, this would be the person I would listen to about this, he's been identifying & dealing with it a long time.

Dark Purple Disease Affecting New Growth?

Theres also different varieties of Phytoplasmas, thus different symptoms, though I do acknowledge Ive no no verified phytoplasma verification. I can tell you though, its insidious, and is also passed to the seeds, if any plant makes it far enough to produce seeds ect. It also eventually turns...

The Phytoplasma, also causes the potatoes, to turn black.

Seems like for the 2 different species of plants-Potato-Alfalfa, it turns alfalfa yellow, and Potato Leaves, mottled Purple, and the actual potato, black.

So, its seems the phytoplasma, affects different plants, in different ways. IE, color differentiation. Even though its the same Phytoplasma.

But, it seems in most cases, in all other plants mentioned, it is spread by mostly leafhoppers. THEY are the one main thing that always is mentioned.

Another bad thing is, there are more than 22,000 different species, of Leafhoppers. One of the most diverse insect species rich, plant sucking/eating bastards known.
They are a Cicadellidae species.
Ive also read, that the phytoplasma, can overwinter, in Elm Trees, for one. Then when the insects come in contact, the get infected, and spread it. And it takes time, for plants to show symptoms.

Below are purple leaves, on a potato, and a black/purple potato itself. Kind of goes along with
Weed leaves turn purple black, and the buds end up black/stunted.
Though, this purple is a different shade vs what Ive seen on weed, the different shades, may be plant specific. Just like the Purple Top affects alfalfa by making it yellow, and potatoes, a shade of purple, plus, it turns the potato, black. The potato, will start out light purple, often in spots, and progress, to black/purple.


Purple top disease In North America, this pest is known to cause potato haywire disease and is classified as an A1 quarantine pest by EPPO (OEPP/EPPO 1984) [25]. With the exception of the first one, all of these pests are categorized under the 'aster yellows' group, characterized by symptoms such as yellow or purple leaf discoloration. Typically, they are not transmitted through tubers. Leafhopper vectors responsible for their transmission include Macrosteles and Hyalesthes spp. In Europe, numerous phytoplasmas of the aster yellows type are found, infecting various hosts. However, only the potato stolbur phytoplasma is detected in potatoes, and it is generally recognized as a distinct phytoplasma strain. In Australia, several Asian countries, and the USA, the tomato big bud phytoplasma causes a disease that closely resembles stolbur. Additionally, three phytoplasmas in India are identified as belonging to the Old World aster yellows type and are differentiated from the potato stolbur phytoplasma. Potato purple-top wilt phytoplasma shares a close relationship with the aster yellows phytoplasma complex, which exhibits a broad spectrum of hosts. It can infect approximately 350 species spanning at least 54 plant families. Apical leaves exhibit symptoms of pinching, curling, and the development of yellowish-purple pigments. This leads to a loss of apical dominance in infected plants, causing a proliferation of axillary buds. The affected plants may prematurely wilt and die, often producing hair sprouts. According to Conners (1967), the main symptom is the occurrence of purple-top wilt, with the haywire stage attributed to secondary infections. In its natural habitat, potato purple-top wilt phytoplasma may spread through its leafhopper vectors. On a global scale, there is potential for it to be transported via potato plants or the insect vectors that are linked to them, although such transmission is rare in real-world scenarios. Conclusion ZC disease has now established itself in multiple potato-producing regions worldwide. The suspected causative agent, CLso, has the potential to infect other economically significant Solanaceae crops, posing an even greater threat to the agricultural industry. Integrated pest management (IPM) strategies, including chemical, cultural, and biological controls, have been put into action to manage the psyllid vector population and curtail the spread of ZC disease. However, a need for long-term solutions remains evident. Recent advancements in potato genetic resources and crop improvement technologies offer promising opportunities for developing new potato cultivars with innate resistance to the psyllid and/or CLso.

Yeah! Very bad thing to have in your neighborhood! Probably almost impossible to eradicate Without a united neighborhood effort! And what are the chances of that happening! So now you’re just roll the dice!

If you live in Close quarters everyone else has to also! And it Infects, different species of plants! Gnarly! All it takes is Tim down the street to try and push his plant through it And the hoppers swing by and load up on it! To negate anybody’s effort! Gnarly! L O L
