Anyone out there familiar with this problem besides me? Some sort of dry mold

Hey folks. Just finally reaching the tipping point here and thought I’d ask around the forum to see if anyone can help me. Surely I’m not the only person in the world who has this problem? Google hasn't given me any results.
I’ve been dealing with this issue for a few years now. It only happens to one strain I grow- the ever troublesome Pineapple Chunk. P Chunk, the strain I love to hate, is a very fine smoke, but the plant itself is a total pain in the butt to grow. Out of all the strains I’ve ever grown it’s by far the most prone to budrot, aka grey mold. It’s also sticky as epoxy glue, stinks to high heaven, and grows like a insanely tangled floppy vine. It needs constant trimming to keep it semi-manageable- usually once or twice in veg, and 2 or 3 times in flowering. I practically need to wear a moon suit to do this job, or I will stick to everything in sight and stink for days. Yuck. Honestly, I’ve been trying quite hard for years to get rid of this strain. In spite of my best efforts chasing down new strains, sadly, in the end the PC is still the best bud I grow. :(

On top of the problems I’ve mentioned, it occasionally gets this other issue. I’m quite sure it’s not budrot, or at least not the normal kind. I’m very familiar with budrot since I live in an extremely humid area and have battled it for a decade or so. If it wasn’t for my dehumidifier and a lot of fans my whole flowering room would probably be taken over by it. As it is, I rarely get it anymore, except sometimes on the P Chunk when the air is extra humid.

This problem seems to favour drier conditions. It starts on the surface of the buds first. Initially the sugar leaves will take on a limp appearance and lose a little colour, as in this picture.

As it spreads, the buds dry out and turn pale yellow/white. The trichomes seem intact. The end result is bud that is bleached of colour and dead- completely dried to a crisp. There are no spores visible. The problem spreads from the outside of the bud, usually the tips, and travels inward.





This is opposite to the gray mold as I know it- in several ways.
-Gray mold rots the bud and turns it wet and slimy. It completely ruins the area it affects, leaving no visible trichomes.
-It usually (though not always) hides itself and starts from the inside of the bud, near the stem.
-When I touch a bud that has advanced budrot/grey mold, I can see a puff of spores fly up. Not so, with this other problem. None to be seen.
-Budrot thrives in humid conditions, while this other problem occurs in dry conditions.

Thanks for any help. Cheers. :passitleft:
 
Seems like a pH or a mineral issue, leaves drying out, losing chlorophyll, slowly dying rotting away... Is it obvious smell wise? Do you snip it out and smoke buds? Or they rot to core?
 
Definitely not caterpillars Dr D, as these are indoor plants and I don’t have any pests as of now. Caterpillars are also quite scarce in these parts, believe it or not. :passitleft:

Thanks for the tip Ms Bird. You’re right- Mr Krip knows his stuff. He also stops by my journal once in a while and I posted the problem there also, so I think he will probably get this.

I detect no difference in smell Grizz. I don’t think it’s a ph issue as I’m pretty sure I’m on top of that, and my other plants have no similar issues. I can see why you’d think so from the pics, but really it doesn’t seem like a nutrient issue at all. It’s a contagious thing that spreads in late flowering, similar to grey mold in many ways- but... different. It spreads from bud to bud. Not just in the core necessarily- it tends to spread evenly and infect the whole area as it goes, turning it crispy. Since the trichomes remain intact and I see no spores I usually toss it in the pile for making bubble hash with. I don’t get it all that often, but it’s been especially annoying on the PC this summer. Possibly because it’s beeen drier here than usual- I’m not sure. :hmmm:
 
I've heard the calls! :ganjamon:

Just got to my desk. Give me a few minutes to take a hard look but if I had to guess, I'd say possibly Brown Blight or some virus.

For starters, here is a very good article on types of diseases effecting cannabis (note the chart!):

Diseases of Cannabis

Once I get settled, I'll do a little research and see if I can get you closer to an actual answer. ;)

:Namaste:
 
Sorry for the delay, but have been slammed with work all morning.

The only time I've seen damage similar to that, personally, is when I had some plants too close to the lights and it pretty much just happened with the top buds.

I know that's likely not the issue and the lack of "slimey" stuff, means it's probably not something like budrot or caterpillar damage which would also be suspect, and is why I was initially guessing at either brown blight or some sort of virus.

Brown Blight, I believe, tends to occur later in flower, which, if I understand correctly, is when this is starting to show up in the plants. Problem is, I've never actually seen it and there are very few pic's on the web showing exactly what Brown Blight looks like and, what makes it more difficult, is that "Blight" is actually a bunch of symptoms that can be attributed to a wide range of fungi.

But, there are no spores and, if it's not a fungus, the ONLY thing left I can possibly think of is some sort of virus.

I'm sorry I can't be of more help on this one, but will ask @Norcaliwood, @Doc Bud and @Dwight Monk if any of them can possibly provide better info and I'll continue to see if I can narrow this down better.

:goodluck:
 
Tead you throw to many darts, maybe you hit something but only maybe...no spores no smell, fungus it isn't but only my opinion. Sticking to what I said weasel and yes by sight of photo.. your water is not too cold...I d go with a longer feeding to harvest, dropping ec or exact opposite, longer flush..
 
Wow. You found an odd one

I think it found me.

What happens when you tap the bud over white paper

Just got back home. I’ll check that out in a while and take the microscope to the results.

Another thought.... tried any mold prevention sprays or other products yet?

No. Partly because I don’t like spraying unless I really have to, but mainly because I wanted to get some idea what it is first, in order to treat it. This is probably the worst case I’ve ever had of it.

One more thing... you can call @Mr. Krip by using the ampersand before typing anyone's name. It shows up as an alert.... kind of like this one @Weaselcracker .

Yep. I just figured I’d let him find his way here from my journal so he wouldn’t feel obligated, in case he’s busy or something.

First, it kinda looks light burn. Got any hot spots? Did the buds droop into bad places?
Second, the death seems located to parts of buds. Does it spread and eventually consume the whole bud? That would totally indicate fungus or mold.

Yeah I totally agree it looks like light burn. But it isn’t. It afflicts all areas of the plant, not just the top buds- so it doesn’t seem related to light or heat. It doesn’t seem to target any specific part of the plant, though it often does start at the top. Lots of lower bud gets badly affected as well.
Yeah Tead it will eventually consume the whole bud as it spreads. In the picture I took which shows most of the plant, I’d already clipped off the worst afflicted buds in previous days.
