It aint no Phosphorus Deficiency.
We have perfect PH, and our soil is amended with 20-20-20 like farmers use, and also 0-0-52. We also use Azomite, and Kelp.
And we amend 20-20-20 in the soil every 6 weeks. 0-0-52 every 2 months, and Kelp every month.
And the medium is either native soil, or Promix BX in 20 gallon containers. And some plots are 20 miles apart.
And there are humongous numbers of leafhoppers in the area.

Don't be stressed out. If you can find some sort of cannabis botanist, someone maybe with commercial grow experience that's seen these kinds of things before, I'm sure someone will speak to you about this. If you're really thrown off by this thing (I'm still curious if you've tried just leaving it alone), maybe try a different patch/area next year? Use different soil, and try other strains.....then see if it happens again.

Wow I can't believe you spend so much money on soil. 50 gallons!?

Harpua88 said:

How much do you think that costs? $100? Less? It definitely matters if it's bought as 10 separate bags, or in bulk...

Hey James ,, are u in VA.. or on the east coast? I'm near culpepper VA.... This is prime farming country.. and although I haven't checked my soil, my last crop that I was able to finish, cane out great

Yep.. I. Going try try a different area next year... This year I've pulled up ones that even hinted at getting this disease.. but last year the one plant that had it bad eventually succumbed to grey botrytis.. I think it weakens plant and opens it up to other pathogens... It's hard NOT to pluck out the bad spots... I'm such a nervous gardener when it comes to weed... I count on this patch to get me and my family thru various medical issues.,

Does the discoloration extend down into the stem of the plant? Do you see variation in the stem veins’ color? Or is it only between stem and leaf ti

I totally get your fear, but you'll never know it's something bad if you don't at least try leaving one alone to see what would happen. It's sort of like you think you might be allergic to chocolate, but you've never had it. Believe me I don't want you to have some serious problem that spreads and causes increased havoc all around......the fact that you've had good harvests overall is a good sign. The plant that succumbed to botrytis......I'm just playing Devil's advocate here, but maybe it wasn't this issue that weakened it, maybe it was all the plucking. ;)

I don't know, I'm just curious to see what would happen if you let one plant develop on its own.......would it spread? Would it quickly outgrow it?

Also, is there any genetic relationship between last year's and this year's plant(s)?

Spotsy said:

No relationship genetically.. that's what is scary,.. last year's was the Acapulco gold,, this year it's some Stardawg.. as a side note. I planted some sour diesel bag seeds, and they all seem super healthy this year... The ones that got the black rot, as I call it, were the expensive seed bank seeds.. I'm going to try your idea of leaving one of the infected plants alone.. but I'm going out right now to transplant it a few 100 yards away from the main crop... I'm on 6 acres,, so I can move things around , and still have good control,, light ,, etc

Flowering in mid-May? But yeah I'm interested in what happens if he just left one of these plants alone and didn't pluck.

Weve left em alone many times, and most of the time they die, but sometimes they grow out of it,, or partially grow out of it,aand end up deformed.

Dont leave it alone if its around your other plants. This shit is highly infectious, and dont touch any plants after youuve touched an infected plant, and if use have used scissors on it, or anything you may use on other plants, thoroughly sterilize the instruments that have been in contact with this shit.

Like I said, we have been battling it for about 10 years.

Last year we lost some really impossible to get seeds.
2 packs each of the following strains from Crickets and Cicada. More than $1000 worth of seeds in the C&C alone

Crickets and Cicada
Puck BC2
Pacific Northwest Hashplant x Puck BC2
Lebanese Hashplant x Puck BC2
Sensi Star x Puck BC2
Nepali x Puck BC2

Plus

Mr Nice Super Silver Haze-50 plants

Super Silver haze x Shit-65 plants

AKBeanBrains

50 NL1 plants
40 NL5 x Haze
40 Tk/NL5 x Haze
40 Sensi Star

Authentic Genetics
40 NL2 plants
50 Sk1 Plants
40 NL5 plants

Jaws Cherry AK47-40 plants

Thats 400 plants or more.

Plots of 20 miles apart. Many of them on the banks of the Big Sandy River-Levisa Fork, and Tug Fork.

Also the Ohio River. And Daniel Boone National Forest.

Some of them in my buddies backyard in containers of Promix BX.

Every plot had casualties.
We probably had 75% Fatality rate. This also included Male Plants.

I got deal on 20 bags.. the manager at Ace hardware is a dedicated grower.. and I worked it out . Got em for like 18 a bag... There retailing for 25 this year .. I know , it's expensive. But until I start making my own.. it is what it is..

Nothing has worked. And NO, I cannot 100% certify that it is a Phytoplasma.

When I say weve been battling it, its been a losing battle.

And all those above mentioned seeds/plants, was just 1 year out of 10.

And IF it is a Phytoplasma. The only solution is to keep all bugs off of the plants. Especially Leafhoppers. But any insect that sucks the juice, or chews on the leaves, can transmit the disease.

Also the bacteria can over winter on certain plants, and trees like Elm, Alder, Paulownia, and others.

That's funny. "Bad cultivation".....

Hey thanks for that thought.. yeah this is some weird, non typical thing.. I just kept plucking out the whole top last year on affected plants. ,, But only one plant outgrew it.. I pulled up all but one of the affected plants last year.. and the one that outgrew it was a chocolope. So aggravated.. I figured it was a one off situation last year. But apparently not. I already had to pull up some this year.. so whatever y'all can help with this year

Hey there.. sounds like you may have had some experience with Witches Broom. I fear it's what I'm up against.. care to take a look at some pics and weigh in? I had some tarnished plant bug (and possibly others) pressure early on that I didn't aggressively combat and I fear I'm paying the price as I believe they're categorized as "leafhoppers." In 13+ years I've never experienced anything like this.. major lesson learned this year. I also ran some Dr Zymes (citric acid-based pesticide) through a used sprayer about a month ago and have since read that herbicides, even in low doses, can result in Witches Broom. I'm not sure what the sprayer had been used for prior and I fear I sabotaged my grow. I rinsed the sprayer out and ran some water through it prior to using it for Dr Zymes. Although I find it hard to believe that trace amounts of ANY herbicide could result in the situation I'm facing, I can't help but return to the fact that I sprayed and then started seeing symptoms. Anyway, here are some pics.. thanks for your time.

Woah!!!! Thatsucks regardless of what it is.

First off anything I say is only guessing, and am not qualified to be relied upon in the area of virus, bacteria, viroid ect.

To me, after looking around a bit, I believe 100% that what you have is witches broom.

Certain Herbicides can indeed cause witches broom.

What you have is most likely caused by some fucking bug. And number of bugs can cause it. Leafhoppers, mites. Any chewing bug.

deadbeet said:

Thanks for the response. It’d be sorta crazy to think that any trace amount of herbicide (were that even used in the sprayer prior to my owning it) would wreak this much havoc, no? I’m obviously trying to put that notion out to pasture cuz otherwise I can’t stop beating myself up over having used that mf sprayer!

I too doubt the trace amount of residue left after you washed it out was enough to cause anything.
Virus, Viroids, Bacteria, Fungus, Mold, Insects ect, are going to be downfall of Weed, Hops, and Fruit, and Vegetable crops in the future. Its already happening.

Me and another buddy been growing weed since 1972, and never had anything like the purple shit that attacks the growing tips, and works its way all over the plant, and kills it in most cases.
Starting about 10 years ago it started showing up, when in the previous 40 years we really never had any problems. A bit of mold late in the year. Now every year for 10 or more years we lose up to 90% of the crop to some purple plague. And we are in an illegal state, and have to work our asses off to get anything, and we aint young. Especially him. Hes 74. Still diggin hjoloes, and carrying water.

And YES, weve been attacked again this year. Much of it just now starting. Just before, and during preflowering is when it is most likely to start, though I have seen it in early July, but not very many times. 99% of the time with the strains we work with the shit starts in August.

And it never happens to the same strains grown indoors. You can take a nice healthy clone from an inside mother that never turns purple indoors, and take it outside, and it August, the motherfucker turns purple black, and dies.
