Get yourself some Safers Insect soap and spray the entire plant on both sides of the leaves every 3 days. I've use this on broad and russet mites and it can be used in flower.
It works on the mites and the eggs on contact and will leave your plant mite free and healthy. I use to use forbid and avid and they work too, but I still had to spray it multiple
times. These are locally systemic, meaning they don't protect the new growth, but penetrate the leaves and stays locally. You also can't use these in flower.
True, but you mix at 20% and if it helps...Just think how much Milk it would take to Drench 50 nice plants. Especially when you have to make sure the Undersides of the leaves are the first to get drenched. Takes a lot of liquid. A lot. The whole plants literally has to be dripping. Undersides in particular.
I followed you here from IC.
FWIW, when I had this same issue a few years ago, I spent a while looking for bugs under my microscope and didnt find anything. So I'm not convinced it is broadmites.
It definitely seems to be making its way across the country. I stopped sharing clones shortly after I experienced it and havent seen the purple death in my garden since, but i still get other fungal issues occasionally due to the high humidity. I grow outdoor in pots, in Hawaii, where it is warm all year long.
It's not temperature or nutrient related...this thread could be about 7 pages shorter if people stopped insisting it was.
Someone on IC tried to get the University of Hawaii to look at it but they wouldnt touch anything cannabis related. Need to get a sample to a skilled plant pathologist in a rec state, so we can finally get a positive ID on this issue.

Im convinced what the photos show, and what Ive seen from my buddies stuff, it is Broadmites,/Phytoplasma, and if you don't have a really good scope, you wont see them. They can ride in the back of a spider mite theyre so small. Most say you need at least 100x microscope to see them, and then you wont always see them, because if they are in the nymph stage, they will be living inside the plant tissue, and invisible to a scope.
Ive also shown the photos to some very experienced growers in Cali and they also say it is Brodadmites. Gascanastan from Swami Organic Seeds also agrees, and is the 1st to suggest Broadmite Phytoplasma.
I have been successful every time I use it and its saved my grow. You have to hit it every 3 days with complete coverage and use a good scope to monitor it progress. You alsoActually I've used this stuff previously on mites/aphids etc. with not much luck, Malathion worked much better for me. That is my experience.
I do have a good lab microscope and broad mites can get up to 0.2mm in size. I didn’t see anything when I had it. Also, broad mites were quite common in indoor gardens a few years back and there was not really any reports of purple new growth.
It takes a skilled plant pathologist that can look at a particular sequence of a plants rRNA to diagnose Phytoplasmas so it’s a lot more involved than looking at a photo of symptoms. I have leaned towards it being phytoplasma for a long time but as of yet no one has made an official, science backed diagnosis.
Just stopping in to say I have been told the University will not test this for me even though it’s legal here. I have referred some knowledgeable folks to this thread and am hopeful they will look into this and give us their thoughts. I was under the impression Broad mites could not overwinter in a cold climate like I have here and were mainly an indoor/greenhouse pest this far north. My plants have never been indoors or in a greenhouse and I live far from from any agricultural areas. Not saying it is impossible for it to be BM’s but I would think it highly unlikely in my case.
A couple years ago, @by_stokes on IG had a strawberry banana cut suspected of TMV tested by Heather Vallier Ph.D of Crop Doctor Laboratory. She confirmed it was indeed Tobacco Mosaic Virus.
I just looked at her website cropdoctor.net and it doesnt mention anything about phytoplasma detection specifically but she sounds like a good place to start.

Please keep us posted on what she finds.I’m having the same issue with plant I moved outdoor from indoor with no previous purpling. Then took cuttings off it and moved them back indoor. Still very dark purple growth tips.
I was talking to someone with a PhD in plant science she said to send a few pics so I will see what she says.
