Suspicious Branch, broken or fungi? Would you amputate?

[TSD]

So this one branch has an issue, it looks like it was broken and is healing, sort of, but it also has this weird necrotic looking bit on the stem. I feel like I would have noticed a break, unless it never flopped over... I'm out there a few times a day. We did have some wind last week. It just looks suspicious to me, the whole arm is lighter in color and sickly, even the hairs are grayish. I'm worried because I went to help my pops with his girls, and he had fusarium wilt on one whole arm, a third of the plant. I told him to amputate and I ordered some trichoderma fungi for him to hopefully keep it in check till harvest. My branch is showing similar symptoms, but those also happen after a break when the vascular system is damaged. What would you do? Amputate, or let it ride? I don't know if one arm is worth the risk if it's a fungus.

Boring caterpillars?

Eh feck, I hope not lol... maybe I'll just hack it off.

The only reason I haven't yet is because it's not "wilty" and it does resemble what happens when a break repairs... it's the weird brown stem that's got me confused.

Can't make any recommendations. But me being me, if it were mine, I'd take a razor blade to that spot and look inside.

I have had quite a few bend over and they form knuckle very similr to cropping but i have never seen like you have ever in 30 years..this is the second time ive seen this is as many months..it hasnt had any string around it has it..its def not a normal heal if thats been damaged..every branch that ive seen heal from bent over has never stood back up erect like that.cut it off if you like..it looks nasty

I think I'll go perform exploratory surgery... wish me luck.

It could be a break that's repairing itself that has become infected. I have saved broken branches, but I don't remember seeing that discoloration or swelling. It's almost like an abscess. I have seen something like that on fruit trees, in which case the advice usually is to cut off the branch and put it in the garbage--not the yard waste or compost!

 

[TSD]

Well, exploratory surgery turned into an amputation, mostly because I explored a bit aggressively lol. Inner xylem looks healthy, no signs of critters, but that doesn't mean there wasn't a pathogen in there that I can't see... I think it was a break that healed weird. Oh well, it was a very lower branch that I worked up through the scrog anyhow... Guess we'll have a VERY early blunt to try in a couple weeks... Super Silver Haze is one of my favorites and I've been out of it for months, so I'm ok with it. They're starting to get a smell and thicken with trichomes, so should get a little buzz at least.

 

[TSD]

Ok so this is the year for weird shit apparently... now I'm leaning towards fungus, completely different plant, wasn't broken that I've seen. Amputate? Sonofabitch. I feel lime the hairs are prematurely browning too... definitely something not right.

You could try using some kind of beneficial bacteria/fungi to displace the disease but I would be more worried about getting rid of the bug infestation.

Yeah I have done that already. I don't have an "infestation." It's impossible to keep every bug off outside.

What products have you tried for the rot? Some are definitely better than others. But yeah depending on where you are growing the pests come in all forms shapes and sizes. Especially when you have a wet garden oasis in the middle of a hot dry summer. That sucks you are dealing with caterpillars, I feel for you. There are these different types of fungi that are know to infect and kill certain bugs.

TSD is in one of the northern New England states. I imagine weather there at night is consistently lower than dew point now. It has been here in Michigan almost nightly since we entered September. If the plants are not drying off during the day and the days are remaining cool, then I concur with @TSD's suspicion that this is fungal related. We're not talking about an inexperienced gardener. She's pretty good at what she does. Unfortunately when mother nature is involved, you can do everything right and still run into problems.

@TSD I'm also curious at what products you're using. I'm not 100% sold on "never use a spray on flowering cannabis." It's mostly true you shouldn't, but sometimes its your only option. You do need to choose your products carefully though.

Yeah as far as spraying flowers with microbe products, I do know they will fail tests if there is certain microbes on the bud. Not sure which ones or whatnot. Thats one of the reasons I like the targeted inoculants versus a raw compost tea. If you have the capacity for washing the buds during harvest I guess H202 would kill anything on the surface at least the plants that need to be treated. Ounce of prevention worth a pound of cure,

I have the same exact thing on 2 of my outdoor plants, the 1 has a droopy top now because of it, and i hacked off the other plants nasty spot. Ive come to think that its these little buggers called buffalo treehoppers. They get on my stems all the time and they are actually a sap sucking bug so thats what brought me to my theory. I could be totally wrong but im just letting mine ride it out from here. Hopefully it doesnt bite me in the ass

I alternate Loast Coast plant therapy and BT... and try to avoid the buds, I've cut back now that we're really in flower. My dad has fusarium and I never had this issue until after I was helping him, so I'm worried I somehow infected my own, even though I was careful. I bought this for him after I figured out what his was... mine I just found today, well this last one anyway.

Ok, well you are not using any beneficial bacteria so you won't be getting any of the anti fungal and anti bacteria benefits of those, which looks like what that is on your branches. Micro root is just Trichoderma which is everywhere and in all soils. Lost Coast therapy is just a natural blend of plant oils. OK so my suggestion is using an inoculant product that has a wide host of beneficial bacterias and Mycorrhizae, that you can use as an actual soil inoculant and as a disease remediation spray for your fungal problem. I have seen things similar to this and using those products is like magic, completely gets rid of it and restores the rot spots to normal healthy growth. I can suggest some products but I don't want to come off like Im promoting any products. But anything that has Bacillus pumilus, and/or Pseudomonas alcaligenes.

I have a mix of last year's homemade soil and ocean forest. I top dress bat guano. I use Dutch Science nutes that have all kinds of good shit... I should have some beneficial stuff going on in the soil.
