Aloha everyone
We are dealing with horrible issues we nicknamed "black death" here in Hawaii. It affects both clones and seedlings. Let me describe.
The "black death" is easily identified in growing tips on any plant affected. The new growing tip is twisted, sometimes mutated, hooked leaves that have turned a dirty black/purple. Growth will be stunted and leaves start to grow bizarre serrations, bumps and strange looking mutations in veg.
Once one plant has it your whole garden will get, some faster than others, all stages, all sizes.

When these plants are put into flower they hardly stretch , have no real smell and no frost or pistils. The stretch growth is sometimes what I have heard called witches broom.Sometimes they grow all candelabra style..

Buds grow leafy,small and stunted with the black/purple tips becoming distorted and mutated. Yield is pathetic..

The plant is utterly worthless and ends up dying if I dont kill it first. I have duds like I have never seen before.

Screams broad mites or russets to me right?

Except.....
NO kind of spray I have used has completely stopped it yet. I can cut plants back to smallest lowest node, change soil and reveg and it comes back without fail.
If Hawaii had a lab to send samples , it be da first thing I do, no such luck yet in paradise.

I have tried both chemical and organic methods.

Here is a list of what does not work so far.

Avid
Azamax
Actinovate
BT
Neem
Organocide
Saf T cide
Triazicide
Spinosad
Nuke Em
Natural Mystic
35% pyrethrum
Im an outdoor/ greenhouse guy in Promix BX.

We have tried everything listed and suggested, no sucess.

I got tons of pics from newly rooted clone to about 4-5 weeks flower that I cannot load from my phone, so that will have to wait.

Last thing, I have read most of the broad, russet and cyclamen threads, same goes for root aphids and stem nematodes and I have never personally seen anything like this yet.....

I know it is hard with no pics yet, however anyone got any ideas off da top ya head ?

First, get a scope and verify that you have pests.

[meadowman]

look into verticillium wilt....just a guess from your description.

Yeah "sounds" like a fungal problem. You could try mixing organic cornmeal and water. Soak overnight. Strain off cornmeal, spray plants and water them with it.

Texas A&M noticed in their field trials that peanuts grown on fields that previous crop had been corn, that they didn't have fungal problems on the peanuts. More testing and they now recommend applying cornmeal on lawns for Take-all Patch and Brown Patch. This is their 1st choice fungicide that they recommend over chem fungicides. People use it successfully for treating Toenail Fungus. Cheap solution, worth a try. Good luck. -granger

Looks like you have tried many different pest remedies, but I agree that it seems like a fungal issue.

A way to think about fungal problems is that the surface of a leaf ismade up of a bunch of tiny cups. You can either fill them with good stuff, or bad stuff is going to fill the cups.

Using a high quality compost tea weekly(foliar sprayed) is a way to fill those cups up.

When you are already under attack sometimes you need to try something else. In the past I have used OG Biowar foliar to basically fungal the shit out of the leaf surface. I have applied it very heavy, and it has stopped any issues that arose.

I am sure you can get a comparable product. If not, they do ship.

I personally use a neem essential oil blend once weekly, along with a compost tea once weekly. It seems to do the trick.

Just remember that no matter the problem you can and will find a solution. Once you do, you will be an even smarter farmer.

Mile's suggestions are good. I like ACT and OGBioWar. I'd try them too. Maybe alternate. Good luck. -granger

Og biowar is no longer sold on the big island to my knowledge. Bummer cause i sure liked it. Anyhowz i have witnessed this black death (i call the no bud disease). Like jojo say the growing tips turn purple and distorted. It looks like broad mite, root aphid, and tmv damage all wrapped together. Massive nutrient and ph related looking issues, brittle tissue, plant likely to dudd. I saw it pop up a couple years back in a friends garden where i was staying. He tried all kine stuffs to fix. All to no avail. Some recovered slightly but dudded out in the end.

Post some pics of the damage. That will help us determine whether it is broad mites or not

This is early stage in veg.
