Purple/Black Disfigured Growing Tips/Buds

I have encountered this issue every year for the last 3 years outdoors in MA... at first I thought it was from red ants, because I basically grew on top of a large nest, but this year I got rid of the ants and I have the issue once again. Doesn't matter what the strain is, I do different genetics outdoor all the time...
Same here ( Mi.)

So your thinking its the purple curly top virus.. which is caused by a leafhopper?
I think it's the virus first noticed in the upper Midwest on potato plants, and it's been transmitted to cannabis via leafhoppers or some other insects.... the thcfarmer article from a few years ago nailed it...I know a few other locals who have experienced it, but it's sporadic...

I was told by DCcan it probably was pctv and was caused by a leafhopper that was affecting mine.. im just not getting that bad of curling and twisting ( barely) and its not spreading.. just a couple tops on a couple plants..

No I dont know if it is, or is not purple curly top virus. I just think its some kind of virus transmitted by leafhoppers. Ive never seen verified photos of weed infected with curly top virus. Not saying its not Purple Curly Top virus, but Ive never seen photos to verify it is.

My buddy has a problem. This is an outdoor grow.

Each year for the last several years, my friends plants Veg great. No Problems. Beautiful, huge 7ft tall 4-5 feet wide Mr Super Silver Haze. Weve been running the clone mother of this plant, inside for 3 years, and its as good as it ever was.

My friend made some seeds from F2s from this plant I made, and we have also grown at least 25 out inside and never any purple/black.

He then crossed my F2 with his 1988 NL1/HP x Hawaiian/ 88 NL5/Hz x 88 NL1/HP x RKS.

I grew 1 of these inside, and it did the same thing, and I NEVER have a PH problem. I use Promix BX. Mine also vegged normally

When they start to kick over into flowering, the growing tips, start turning Black/Purple... and not in a good way. This aint the normal purpling ect. It is totally deforming/disfiguring, and ruins the plant.

#1 my friend doesn't use lime, he should, but has been growing 35 years, and never had to use it, and has never had this problem. The new forming buds/tips/leaves look like the plant has bud rot. But like I said. I ran a tester inside, and it turned Black

I'm still guessing that its some kind of nutrient lockout, or it could be that his NL1/HP has a virus that's passed on, and not visible until they start budding.

Ive told him I think it could be PH/Nutrient lockout problems. Could it also be possible that it may have a Calcium/Mag/Phosphorus deficiency because No Lime PH troubles ect??? Causing deformation ? I'm also sure that more nutrients are locked out, IF PH is the problem. Hes also yet to run a PH test.

Any Ideas ???

But I'm still skeptical about PH as I said, I ran 1, and it turned black, and my PH was good.
Imo always flush a problem plant with ph adjusted water to runoff once or twice to clear the medium then start over with nutes, Sounds like nitrogen o.d.
If you don't agree adjust whatever you think is the problem.
It could be that the lockout is over also. Look at the newest growth the color should be nice medium green for most strains in veg. This shows a reflection of your adjustments with nutes. Go from there. Also I have never had a grow without a tiny bit of nute burn on the fan tips. It's normal, a little stress is good but fix it a.s.a.p.
Happy Growing

Screw all the issues with growing outdoors.
I never tried but just the insect issues from my vegetable garden deters me from even trying. I live in the country area and deer and squirrels are also a huge problem here too.

I get this in my indoor grows average 4.5oz per plant on a 5 month seed to harvest timetable.

Ive been growing weed since 1972, I know what weed should look like, and I know how much fertilizer they need. Its no PH issue, and its not lockout, or to much nitrogen. This started happening 8 years ago, after growing weed for 44 years. The same strains never do it growing them inside, and it usually starts righyt before budding, or in very early budding. Is also not anything to do with moisture, as this year it was really dry when this started. It also happens in plots 20 miles from each other.

Anyone still having this problem? Ive noted some other people on a couple other forums are reporting this problem.

My buddy lost 500 more this year, and willl be lucky to get even a few ounces. He tested the soil for PH, and added Calcitic Lime, and Dolimitic lime. Soil is now 6.3-6.5. Up from 5.8. Plus this is also happening in Promix BX in containers outside. It never happens inside. This is happening in a bunch of different strains.

Totally fucked a few strains that cant be replaced like the Crickets, and Cicada gear. I bought them, and gave them to him. Plus some other strains.

Crickets and Cicada Pacific Northwest Hashplant/ x Puck Hashplant/NL1
C&C Sensi Star x Puck/NL1
C&C Nepali Hashplant x Puck/NL1
Girl Scout Cookies cross
OG Kush cross
NL5 from AKBeanBrains.
AKBB NL5 x Haze
Authentic Genetics NL5
AG NL2
AG NL1
AG Pure Haze
AG Sk1
Mr Nice Super Silver Haze x Shit
Jaws Genetics Cherry AK47
Dominion Seed Company Granny Skunk x Swami Organic Seeds Blue Orca Haze


Every fucking growing tip is turning purple black and twisted. Some plants are 8 feet tall. Huge plants. But theyre junk now, and he may have already just pulled them up.
The Cherry AK47 had the least casualties.

Maybe 5 plants out of over 500 didnt get affected. But the season aint over yet, and they still could turn Purple/Black.

Looks like everyone that contributed to this tread have been gone for at least 3-5 years. Weve had it every year since I started this thread in 2017. And this years the worst. Very first saw it in 2014-2015. Have lost thousands of plants in 7 years.
It also seems to happen right before, or just starting budding, and quickly spreads. I still think its caused by bugs. Possibly Learf hopprers, or Plant Hoppers. Plany Hopers are evrywhere in our neck of the woods. The Green Triangle looking ones. Weve also used Permethrin early on. One time.
Oh man,Shedding a tear for those seeds. So many awesome crosses :(

Yeah man it really sucks losing all of hose strains. The Crickets and Cicada you cant get anymore, and were limited release. It really sucks. I waited forever for those crosses, and barely got them because the demand was so high. So many people on the drop sites waiting for the drop made the servers crash.

I was thinking phos or mag def. But could be that ph is too high for proper fungal growth. Always went by bacteria for veg fungus for flowering. Or l rotate watering from 6.5 to 5.5 which allows plant to utilize all nutrients. Usually use 6.5 in veg then 5.5 before flower onset, with a switch every few waterings. Hope this can give you some more avenues to explore, best of luck!

Its not PH. Been growing since 1972, and this problem started 8 years ago, and has been reported from coast to coast, and as far away as South Africa. All but positive its some kind of virus transferred by Leafhoppers. It never happens inside. I use Promix BX inside, and out and also adjusted native soil. It happens outside in both Promix BX, and Native Soil, but never happens inside using Promix BX. PH is 6.2.

Fertilizer is 19-19-19 Granular-0-0-53. Azomite for trace minerals, and Calcitic/Dolomitic Lime for PH, and Calcium, and Magnesium. Azomite also has Calcium, and Magnesium, as does the 19-19-19. Replentish the 19-19-19 every 6 weeks, and 0-0-53 every 3 months.. Azomite every 6 months. Lime every 6 moths to native soil. 2/3 Parts Calcitic to 1/3 parts Dolomite. Add Calcitic/Dolomite to Promix BX after 3 months.
