Leaves near flowers are turning black/purple

Hi! Help!

The leaves and pistils near some of the flowers on my plants are turning black/purple. I've searched the threads on here and good old Google but can't find a definitive answer.

The details:

• I am very much an amateur.
• I have 3 plants, all the same strain, grown from seeds found in marijuana that I purchased from a dispensary, and was fortunate enough to wind up with 3 female plants. They may be Gorilla Glue #4 or some type of cookies strain. I don't remember the buds being purple when I purchased them, but it was a while ago so I could be wrong. Only 2 of the plants seem to have this issue. It's only (currently) appearing on 2-3 buds per plant, and only there, I don't see the issue on any of the fan leaves. I'm obsessed with the fact that I managed to grow something so I check on the plants pretty frequently and did not notice this until this morning.
• Grown outdoors in soil (Miracle Grow Potting Mix) in 5 gallon black plastic pots with good drainage. I live in Michigan and throughout the growing process it's been consistently between 80-90 during the day and usually never drops below 65 at night. It's very humid here.
• I have not added nutrients to them. The soil I used stated it feeds plants up to 6 months and I figured that was good enough to start. I know this is probably a mistake, but this was a quarantine-work from home-bored and found some seeds-not trying to throw all of my money and time in to this-just want to see if I can do it- type of project.
• I water them pretty much every other day(from the garden hose). It's been hot here and if I go any longer than that the plants start to get droopy. I do check the first couple of inches of soil for moisture before watering.
• They're about 2 weeks in to the flowering stage at this point. The plants are each about 3 feet tall.
• I rubbed a cotton swab on the black area of one of the leaves and there is no residue. I don't see evidence of any pests or mold or fungus.
• The plants have otherwise flourished up until this point so I haven't really changed they way I've cared for them(i.e. adding nutrients).

I included a couple of pictures of the affected buds and one of an unaffected bud for reference.






Are my plants doomed? Should I remove the affected buds? Am I overreacting? Any thoughts are appreciated!

It's normal, especially if temps are dropping. I've had strains turn purple just from temperature alone but for you it's likely genetic.

Here's a pic I took the other day of one of my purple strains:

Relax, it's genetics..

Np, I know that panic when it's your first few times growing. You're all good!

Might be genetic, or it might be what is called the "Black death." Keep an eye on it. If the serrations on the new leaves start growing all fucked up you might have a problem, if not than it is genetic.

I've always wondered what really causes this. I get a few spots on all of my outdoor plants and its always when I spot a few leaf hoppers.

Edited to add.
In my situation -and my plants look exactly like the OPs - I'm leaning towards a phyto infection of some sort brought on by either chewing bugs and/or high humidity swings. What leads me to this conclusion is that it happens across all cultivars regardless of genetic make up. If it were genetic, I think I'd see it inside during winter when my temps dip below 60, but I dont...its only outside.
And those sites usually dont form well. The bud sites dont die back or look like the pics of Black Death, but they're not as healthy as the unaffected sites.

Its a virus which is a cousin to the tobacco mosaic virus. Weve been battling it for 8 years. At guy at THCFarmer just told me today what it is, and he was told by a fertilizer company that supplies fertilizers to large grow operations. He sent photos to the fertilizer company

Its treated with Daconil, and is spread by bugs. Particularly leaf hoppers.

We lost at least 500 plants this year from it. Im going to get some Daconil tomorrow, and see if it works.

The op's leaves do have strange thing twisted leaves, maybe you're correct and it is the same issue you've been fighting.
What's the symptoms and life cycle of the virus?

The earliest symptoms are purpling of the growing tips, and then it spreads, and usually turns a purple black, and then the growing tip can turn brown, and then the plant is fucked. The virus Sometimes goes away, or isnt bad enough to destroy the plant. But most of the time it destroys the plant. The virus is impossible to get rid of once its showing its ugly head, unless youre uck, and it grows out of it, and like I said, it usually renders the plant useless, or it kills it.
Only way Ive heard to stop the life cycle is to use Daconil every 14 days. It also may be beneficial to use Permethrin before you use daconil, but Im not sure about how to apply both. As far as I know you cant mix Daconil, and Permethrin at the same time. I tried calling the Daconil manufacturer earlier, but they were closed. I will call them tomorrow, and ask how to use both permethrin, and Daconil. But Permethrin stays in the plant u to 40 days, so you cant use it during budding. But you have to initially keep the bugs off of them.

Update.

The guy said he caused confusion.

He said the Daconil was for fungal diseases, and not the virus. Daconil is useless.

He said he has been using Chelated Potassium, and Chelat5ed Silicon. It looks like they are super expensive, and hard to find.

Sorry for the confusion.
