What is turning these Purple?!?

[Joebuds]

Hello, I have new growth that is turning purple. Is this the beginning of grey mold? Doesn’t seem to be hurting the growth at all. Any info is appreciated

Looks like moisture burn from morning due on the leaves, sun comes out and burns em

Unfortunately I have a thread to refer you to, I hope it's not the same thing, but it's something you should check out! Good luck

Dark Purple Disease Affecting New Growth?

Has anyone seen this issue before? Temps have been hot: 28-31C Day / 15-22C Night with 75-85% humidity Avg. Appears to be affecting all plants in the garden except a freezeland/timewarp strain that had flowered itself and was in and out of veg/flower all summer. Other than that some 15 or 16...

Thanks for the reply should those tops be cut? I have treated the plant with fungicide

My friend go to the thread: I've read the whole thing I think you should too, and those are the people you should talk with, good luck with it bro

Edit: I just saw your other thread but even more threads aren't going to help, you'll just be more confused. You really need to go to that link and read and talk to those people who have been dealing with this for years because in my opinion you've got the same thing going on, and your info is at that link.

I have read all of that thread... a definite cause was never mentioned... unless I missed it... which I doubt after reading it over 4 times...

I’ll see if I can find some stuff of the purple disease. Are you experiencing this now?

 

[Flint_Fredstone]

Yes.. started on one plant and is spreading. Tossed in some Bloom fert and see what happens. Local guy says it needs some nutes but didn't elaborate on any specific thing. Dif Forum posts say this was happening in Hawaii, eastern Canada, Nevada and Kentucky. some in 2017, 2019, and I see it 2020. At first I thought it was some freaky purple strain lol. Every post seems to describe the problem, then some posters comment on some different solutions, then the thread goes cold. I don't even see anyone say they lost them all, they pulled through, or anything. Its super weird. If I find the cause or cure, I could spend a week updating posts everywhere. Oh and thanks for the reply btw.

Looks exactly like the "purple potatoe top" phytoplasm in coloration. The leaves tend to resemble boron dif.

Think I seen this before.... yup found it.

He didn’t find his answer from that thread. Oldskol said it might be P def. I couldn’t find anything on this issue.

Im going to lean toward a genetic disease that mutates under stress.... Just my blind ass shot in the dark.

Did you spray these with aything? The only other thing i can think of is a hyper production of anthocyanin

Good morning, I see this thread is popping again?!

good because this is the most interesting cannabis thread I've ever read; I don't know what mr. Flintstones issue is, but I know what Mr joebuds had going on above was the same thing as is happening to these outdoor growers in the thread I linked joe to..

it's a great read and I recommend everybody interested in cannabis read it, seems there's some strange unknown purple pathogen affecting outdoor cannabis crops in a big way in certain areas of North America?! Have a great day!

Did not spray anything on them!.. My initial reaction was mold as I have never had any issues with PH using humus and a little fert here an there. It don't rub off!.. I have searched everywhere. Outdoor grows only... from what I can tell which means something environmental. Phytoplasma from insects?... Some dude on the original post "purple disease on new growth" says he knows the cure and is trying to sell the "cure"... Trimmings from the purple affected plants that shows no purple.. don't develop the stuff if the cutting is grown indoors. This is happening from Hawaii to Canada, west and east coast USA, its all over. With the advent of legal smoke in a lot of places, who is to say that this isn't just another case of the government spraying something that will kill unprotected outdoor grows. They actually did this to kill coca in south america.

It could be passed down genetically to not have any resistance to phytoplasma as it looks like some plants may have more resistance. I have no idea where the seeds came from but it would be like a needle in a haystack that 100's of people are growing the same "purple disease" strain.

1. 98% sure this only affects outdoor grows = environmental
2. I didn't see this problem in the 80's so It may be a new problem that cannabis has not had a chance to build up any immunity to yet.
3. People have stated that 100's of plants have been affected with total losses of crops.
4. It has been stated that if they do pull out of this stuff, the yield is only about 5% of what it should be.
5. This is accompanied by purple streaks on main stem starting from lower nodes, wide where the node starts, and the streak getting thinner as it travels up to the next node where it gets wide again just above the node to thin again... all the way up to where new growth dark purple.
6. The plants stop growing at this point.

Just my observations so far. Should the new trick to growing outdoors be to cover all the plants with some sort of small netting to keep the bugs off? I'm being sarcastic but this is serious stuff if we can't find a cure/solution.

Its a long read. Phytoplasmic disease? The pictures look nearly identical.

After 2 years of searching the net for answers, I can't find a definitive cause for this "purple". I'm ready to start looking for testing labs. I have 2 friends growing the same clones. Both have leaf hoppers, same soil and nutes, one spot is fine and the other has purple new growth. Only 5 miles apart too. I do believe this is a pytoplasma of some kind, but might be coming from something else nearby. The expansion of hops growing and/or industrial hemp farms in our area might be bringing unknown diseases to our plants. But only plants nearby or downwind perhaps. I think we need testing to know for sure.

When you have 10 degrees diff between day and night temps it will bring out colours if it's a characteristic of the strain. They normally start to go purple when they are a bit further into flower but I would just keep an eye on it bro. They look healthy otherwise and doesn't boron deficiency make leaves go weird shape?

Nah not that.

What page does any phytoplasm discussion start?!
I’m pretty certain my grow has leafhoppers spreading a phytopasm that causes an anthrocyanin response/purple top. My current understanding of mechanics of it support
-pest control
-good husbandry ofc, and let it try to overcome the bacterial infection bc it’s just a tiny backyard grow, short season. The purple part isn’t the point of infection, it’s a defensive response is my understanding. So won’t clip the tops showing purple..

Found these photos showing it’s possible

this research article. Would love more info, perspective, folks experiences!
