So today I have had to cut some bud rot out but I’m not understanding exactly what I did to create it ? So my question is can some experts please tell me the real reasons for bud rot ..

so my humidity has been up down a little it’s summer time indoor 430 watt led running I’m top watered central of the plant an I’m thinking that was my mistake although temps have been towards 33 celcius some days himidy has remained around 40-50% so I dint think that’s cause . But it could be this is it I have done indoors led 2 years 1 month an yes learned lot but very out of touch with it so still learning a lot to go an probably never end really .
I get that but I’d like a kinda break down on things create bud rot an should I just pull plant cut my losses I cut away all I could see anything suspect even an rest looks reasonable but if it’s going to just keep on degrading due to mould in the tent I want to know so I can save the big sister of her an make sure the few side hustles in there also get zero loss or have no issue with the same issue so I tagged you plankton you have given me good answers bro an correlates with my thoughts so I could use your experience an any others I have had the same kind of responses from would be highly appreciated..
‘I know water is cause ok I get that but in what exact way are roots or down below, is it effected is this why ?
I’m quite lost as to how this came to be I mean we did have some cool days rainy days an humid went up I had top watered an also I noticed some dead leaf in among some buds flowers colas so did I screw up that one week an top watered this is my take on my mistake an id like to know if I’m roughly on it cool weather top watered started mould an then bud rot has spread across from me or from over water my top watering an it started bellow is that possible ?
im lost here people an quite annoyed I’ve had to hack a long project an I want to know pull or leave after I cut anything suspect off ?

Bummer. I know how it feels.

Do you have good air circulation? Oscillating fans inside the tent moving air around?

I removed fan not long ago that was a take on it yeah I was wondering if that was part if not cause for those cool days a water added to the start ?
I have small fan but it’s just circulation air gently an not on plant but above light on the hot centre of the power box for our lights keeping it letting it run cool

In my experience, the plants that are more susceptible to bud rot are the ones with more densely packed, fat colas. Gotta run those relatively warm and dry in flower, and necessary to have plenty of air movement. Defoliate excess leaves. Make sure the colas aren't leaning on each other.

Even though a hygrometer placed somewhere in the tent might show dry, if the air is not moving, or transpired moisture can get trapped between buds and leaves, that makes a place for mold/mildew to take hold. The spores are floating around in the air all around us all the time. If the right conditions for it to grow exist, there is high probability that it will pop up.

Running constant exhaust an air is constant an fresh that’s one of my not quite getting this eh..
‘density on that plant was high I should of taken more off but I thought I had it all seemed like there was enough room but it’s closed up an yeah it’s dense

Having dealt with this issue myself a few times, some things I've learned:

Botrytis (aka bud rot) needs liquid water on the leaf surface to germinate. This can be caused by transpired water from the buds in still air (like not having enough breeze to evaporate the water). That can be addressed by improving air circulation around and through the plant itself.

It can also come from condensation inside the buds, which can happen when you have big swings in temps and humidity (like when your lights go off, the temp suddenly drops and relative humidity suddenly goes up. Look up "dew point"). That can be addressed by increasing the exhaust rate, which will suppress changes in temps and humidity by keeping them closer to the temp/humidity of the room your tent is in.

Dead sugar leaves are basically always a bad sign. If they're not moldy already, they will be soon enough. If I see a dead sugar leaf, the whole bud it's attached to gets cut off.

There are different molds that can affect buds, but botrytis at least is systemic, meaning it can move through the plant's vascular system and affect different areas from the initial infection site, without having to re-germinate. That's why when you have just a little spot of rot, unless you cut it out right away, it'll likely spread to the point where you have a little bit of mold in a lot of your big colas, regardless of your environmental conditions.

You'll get different answers about what to do with a plant that gets rot. I probably wouldn't throw the whole thing out unless it was a widespread infection, but I would definitely break every bud apart and inspect them very thoroughly. If there's any signs of mold or dead plant matter inside, especially on or around the stem, that whole bud gets tossed. I've tried just cutting around it in the past, but found it's not worth the worry and anxiety that comes with doing so. I guess it's up to your level of comfort and risk aversion.

Some plants are definitely more prone to getting rot/mold than others. Part of it is just genetics, and part of it seems to depend on the structure of the bud or how the floral clusters are arranged on the stem. Some plants can be pretty dense and high-yielding, but still have a structure that allows for good airflow around and through the buds. Whereas others just stack floral clusters all on top of one another, and it's hard for air to get in and water vapor to get out.

Sorry for the novel, hope some of that helps...mold is simply the worst and I'm sorry for your loss.

@weedstoner420 gave a much better and more complete explanation.

When I run fat dense colas indoors, i put lots of circulation and run warm and dry especially in latter half of flower.

This past summer, I ran one of the fat/dense types outdoors. The colas very massive and so beautifully frosty. When I harvested, the biggest most beautiful healthy looking colas were totally moldy in the center.

I feel your pain for sure.

If it were me, I'd carefully open each cola and inspect the inside. Cut off anything that's too moldy. If it just has a small spot somewhere, you can trim out that smaller area. Maybe some of it is salvageable, but it's your judgement. You'll be consuming it.

You want great air circulation or you'll get micro climates around your leaf and bud.
Which are dead zones.

Plants need to move with airflow.

As others have said genetics are a major part of it, but if your not blowing air around your setting them up to rot.

Then you've got a sort of scrog so things are packed in, with additional lower buds that should of been removed..
Because that's a dead zone too.

Then you've got plant health.. if they are healthy they are more resistant..

Basically you've created a great recipe for a high chance of rot.

I did cut her out I could literally watch the spreading I get it I see my mistakes now next time this won’t happen I barely ever make the same mistake twice my growing is riddled with many mistakes now I don’t like to repeat them always learning always will be another learnt mistake not to repeat jeeezes thst list must be bible dense by now lmao..
‘luckily saved most an it was close ,,

the smell of the turps on this plant damn they skunk pungent I tell you not a smell I enjoy this one .
much rather a good mango or fruity smell to this skunk lol Bruce banner 3#

You had a lot of dead decomposing matter connected to the colas and buds. Thos dieing leaves and moisture are the perfect situation to get some bud rot going. You can not leave dead leaves inside your living colas. Honestly the buds are not huge. Way to moist or way to much decomp

I see it I get it part of reason this happened I was not able to move around it correctly it’s ok chalk it up one more learnt lesson

Hey guys, good thread and information here
I'm choosing fans and filters right now
Better get the best for the plants
Watering slowly but daily increases rh all the time, may be concerned about it
Best of luck @Sergeant420

Botyritis is not systemic. Under the right conditions it will put out spores that can infect other parts of the plant but it is not moving through the phloem or xylem of the plant.

Google search results seem to suggest otherwise, unless I'm misunderstanding the meaning of "systemic"...
