Not looking good guys. It’s been rainy for the past week here in Toronto, visited the ladies today and found this on one the plants. Is this Bud rot?
I have clipped off this stem, I rubbed it a bit though I hope it didn’t send spores to other sites.

I will be trimming excess leaves and seperating the girls hopefully it will help mitigate the risk a little.

I don’t have rot, I have a real bad problem with white powdery mildew. I keep treating them but the shit keeps coming back, and has overtaken my Amnesia Lemon Kush reveg. Im hoping I can even salvage anything from this years outside grow. Been just one weird summer for growth on them, and flowering has been a headache.

Yes, sorry, it is bud rot.

Preventive treatments are way more effective than dealing with it later.
It sucks and all you can do is try to slow it once it sets in.
The summer here in the northeast has sucked for everything but my hot peppers.

This year I gave a buddy of mine around 40 clones of my best cuts for his outdoor in exchange for a few cases of salsa, jam, and maple syrup. (we barter every year)

I stopped out to peep the girls today. They were all heavily infected with PM. He didnt do any preventatives this year. In fact, the Regalia and Cease I rebottled (with directions) was still sitting on his counter untouched along with the Actinovate he bought himself.
Claims he was "experimenting" :wall:

We're bound to lose a some to bud rot but most everything else is completely preventable.


Sorry to rant, lol. It just really irked me to see all those cuts so poorly cared for.

Like others have noted, thats bud rot. Cut a couple inches below the infection and keep a close eye on the rest. This year has been a miserable grow season here on the northeast coast.

Checked the weather network just now… looks like 50-75mm of rain is on the menu over next few days:| I’m going to place them under a huge tree let’s see if that covers them enough from rain. Otherwise I have a shed I can put them in but not much light in there and I’m worried it will stress them out too much.

My third year growing in the Northeast, but my first crop to be threatened by bud rot. It was a week of cold and damp that set it off. Once you see it on a plant, you will see more of it. It moves throughout the plants vascular system. I freeze right after trimming affected buds, then make ice water hash. Mold spores float, and also pass through 25 micron mesh. But don't smoke moldy buds! A lung infection from live spores...nasty.

Just my two cents: buds don't just turn brown and rot like that. 99% of the time it's caused by caterpillar / worm damage. It's bacteria from them eating then pooping and peeing in your flower.

I've been growing outdoors in the northeast for almost a decade. I harvest late October and the only time you see something like that is when you don't spray the plants weekly with BT. The stuff acts like a shield and prevents caterpillars from getting a toe hold in your buds.

Moth species in the NE will lay eggs on your plants from late June to early October. Thus the need to spray BT once a week.

The bacteria caused by caterpillar waste can create a fungus on the impacted area. It's almost furry looking on the stem.

These are not airborne spores but localized damage. If get you get rid of the worms that issue will go away.

Thing is once you see the damage like that it's likely that more and more tiny baby caterpillar have taken up residence in your colas.

I know this depressing feeling. I do want to say that while I don’t know what to tell you about the buds that if you get mold on the stems I found you can spray isopropyl alc on a towel and wipe it off which seems to kill it

Bud rot (grey/brown mold) can happen inside absent of pests due to the same poor environmental conditions we're seeing this season outdoors. Caterpillars can definitely be a culprit but they're not the only source which is why its important to utilize an IPM with multiple modes of action.
Silicas help. Biofungicides, BTi, Spinosad, even Sulfur is effective (not in flower)

One thing I rarely see noted is calcium. In AG, adequate calcium levels is another way to ensure the blight/botrytis doesnt take hold.

Right, regalia.....spinosad.....silica....... didn't change the humidity and nearly constant rain. This season was tough even for my tomatoes.

This season was tough. We had blight, botrytis, and monilinia infection risks starting very early for the blueberries.

On the upside, we're looking a great cranberry season. The cold really teases out the colors.

The outdoor game can definitely be cruel. I've dealt with mold, powdery, etc.

But it all years outdoors I've never seen damage shown in those pictures to be anything other than caterpillar damage. Their favorite spot to hide is main stem, where flowers develop. You get that fur, stem damage, greyed out.

I suppose if you leave your flowering plants out in the rain anything is possible.
