Some words of advice you didn't ask for. Run a dehumidifier at night. Try to get it down to 50% at night. Don't ever be afraid to remove leaves. Especially in the middle of the plant and the bottom. You can remove 90% of the leaves and the plant will still grow nice buds. But you don't have to be that extreme.
Ive actually though about this. The ac is in no lights mode but im afraid something happen during night. I have taped the screen and buttons and keep still unopened flat fabric pot on top of the panel.

But my 400m3 and 420m3 extractor fans are alwaya on with bull active carbon filters. I always have negative pressure in tent.

I have only courage to defoliate bottom leaves. Those plants are talls aswell you cNt even see the scrog net which is 40cm from coco surface. But i would like to have less foliage and know how in this matter.

Other thing i think i overfeed or something the plants are too happy to change pistil color. Thats why u flowered the first budrot bigbud 11 weeks it never turned pistils but did it right away when chopped. Same here with the infested cola it doesnt look half made anymore.

We actually tested some poor ass oven heated buds and they still had potency after oven so if budrot start to spread i harvest everything, loose potency and yield but atleast have smokeable potent buds.

From my exoerience huge colas cause the budrots its the only strain this happened. But big bud grow so big and powerfull and doest ever herm so its hard strain to skip. But for the next grow i will think about other strains

If i keep watching like a hawk and do my best about the RH i may probably be okay without any further losses since harvest is so close? If i notice any further rot i will remove the part and harvest early on begining of next week when its been 8weeks 12 12

For the next grow i will clean everything very well and do not touch plants bare handed. I try to learn to be more bold with defolition. I just fear the early stress or that i remove the wrong leaves.

I pray this was just a learning point with no major catastrophe and atleast now we have bud drying, getting some early smoke.

Can any1 share their experience when finding budrot did it spread and took everything out or did you just remove the bad parts with no major losses?

Yes, it is entirely possible that if you got it all now and modify your conditions (rh under control, better air movement thru canopy) that you have this at bay long enough to harvest.

As far as defoliation goes, start at the bottom and get rid of any huge fan leaves. At this point in the grow they are not a benefit to the plant, and are only respiring adding water to the air and blocking air movement. It's OK for real. Much better to remove these surgically than more buds!

I have successfully halted bud rot in the past and it was limited to 1 plant out of 6. Yes, it can be done.
And Thank You Moe and every1 who came here fast for the help. I would hug you irl. The fact is with huge electricity bills incoming if this goes to shit we cant possible afford to buy any weed street prices so if i destroed this grow i feel i ruined our lives and left her in pain. Ofc she can live without but life is so much worse and she probably start eating more tramadol and gabapentin and thats not very good. The MJ laws are fucking brutal and medical purpose use is a fucking joke inbmy country with one doctor who describe MJ and even he lost his permission to give descriptions anymore. Opioids and antidesperant drugs are everywhere and not seen bad.

I feel ya brother, the reason I got into cannabis in the first place was also due to my wife's medical issues. We all help each other out here.

Budrot has spread or i didnt notice small spot yesterday different strain sensi skunk. I have 4 plants 2 bigbud, 2 sensi skunk. Budrot found from both bb',s other one was just the tip and first one is the one allready discussed. Now its in sensi skunk too. Or was i hope so. AC is now on 24/7 using to dry the air. I will harvest next tuesday probably if the situation get out of control i harvest asap if everything perfect might even delay from tuesday. Only positive is the oven bud is working quite nicely i checked trichomes witv 30x loop bigbud looks milky good and oistil darken after chop but sensk skunks are not ready. Havent smoken sensi skunk yet but judging by the loop

Ac being on 24/7 i checked and it keep RH ideal temps 23c RH 54% 2.5h after lights out. I should have always keep it on 24/7. Now budrot cannot spread becouse of rotten buds or bad air quality. Harvest may be saved.

I'm gonna add that once those lights go out, I'll bet your RH is spiking to over 70%. I'd bet my $1 to your donut that your nighttime environment (along with genetics) is the primary issue here. Can you take an RH reading about 45 minutes after sundown tonight? I'll bet you will be surprised.
Oh boy... this is not going to be easy to clean, you got a bit of a jungle going on there.

I'm going to make some assumptions and some statements here, you are going to have to figure out what works for you.

#1 - Big Bud is genetically predisposed to bud rot because of the size of the buds and the lack of airflow.
#2 - This is your second grow with bud rot. Need to seriously up the sterilization game between grows.
#3 - There is what I consider way too much foliage in that tent at this stage of the game. Those lower leaves are not photosynthesizing properly any more, but they are working to raise the RH and block air flow, both of which are the primary reasons for bud rot.
#4 - Please don't take this the wrong way - you are just reaching in there handling bud rot with bare hands. In general, working on your plants you need to start clean so you do not introduce bad juju, but right now with confirmed bud rot - you are in emergency mode. Fully gloved, sterile between handling, the whole 9 yards.
#5 - I would cut off the wind right now and carefully eliminate any buds that have rot. Carefully. Do not shake them or drop them, and quickly get them in a plastic bag once you cut them. Spores will get everywhere, and mechanical help to transfer from one bud to the next is your worst enemy.
#6 - I would - after you have carefully inspected every bud and removed the questionable ones, start defoliating from the bottom. I can help walk you thru it if you have not done this before.
#7 - you are going to want to sterilize the tent as much as you can. Everything needs to be clean. Vacuum the floors and the tops of the dirt with a shop vac, but make sure you have a pleated filter in it, otherwise the vacuum can become a super spreader. Wipe down the inside tent walls with w chlorine or alcohol wipe. Fans especially. If you have carbon filter(s) with prefilters, look hard at those and most likely replace.
#8 - Dispose of all the plant material you just took out carefully in a sealed garbage bag outside the house. Empty all the other garbage bags or places near your growspace while you are at it.


OK so now you have done the best you can to stop the rot. What else?

Get the RH down. Somehow.
Keep the fans on. Make sure you have as much air movement thru the buds as possible.
Watch like a hawk for more bud rot to develop. Instantly react if there is any.

Health - please do not smoke or vape any of this contaminated bud. Boytris is incredibly bad for humans, and the moist lung area is a perfect place for it to settle in.

Next - lets just get thru this grow, and when you are done we should look at ways to prevent this and never have this problem again! Prevention is the cure on bud rot.
I agree man! My buddy used to grow big bud a lot & it was always prone to bud rot & moisture problems.

No further spread during night and the air was very fresh when i opened the tent this morning. Ac was on all night. Every day without further spread is a win gaining more mass and ripening. I start flushing today. Maybe wwater only once a day?

Moe! I couldn't be more impressed, I love clear, concise directions!

I am approaching my first flower and these tips are great! Makes total sense. One strain I had been looking at trying was Grandaddy purple, i know that it comes from Big Bud, is GP also prone to bud rot?

I am near the end of my first week of flower, when do u think the best time to defoliate all those fan leaves is? I have only been defoliating the ones that are not getting enough light or are blocking bud sites right now, and have a lot of foliage.

Nice of you to say.

I think GP is generally OK. I've grown it and it does not seem to get as big as big bud, and is generally a shorter plant in my experience. That said, I deploy countermeasures on every grow as part of best practices for growing, and I'm sure for most people even Big Bud would do just fine given the proper environment and training.

Defoliation usually takes place maybe a couple days before flip (lollypop or LST) then a couple days to recover. Then do the flip, and they will still act like they are in veg mode for 2 weeks or more before the preflowers start showing. This is your window to get the plant shaped exactly how you want it and SCROG or SOG or whatever you are doing.

I hate larf and popcorn, those never make it to the end with me so even if flowers start re-forming in areas I have already defoliated - those come off regardless of how far into flower I am. I'll try to dig up some pics from my gopros this weekend.

Im no expert on indoor grows but this is a well thought out and very courteous practical response to your problem, they only thing i might add would be to forensically dissect some of the afflicted buds and scout for very small budworms, yes they are a thing. they are the predominate reason that bud rot starts. A small tan moth lays a single tiny egg on the underside of a leaf, very difficult to spot, then the egg hatches and a tiny brown skinny maggot like worm proceeds into the bud, and begins to feed, their desiccant is what usually precedes the budrot, not always but in a lot of cases. if you have eve seen a moth inside your grow area. this could also be an area to expolre.

Thanks. I think you've seen mine, I got them scrogging, and I need to do a couple more bends to some far reaching shoots, i think it's called supercropping, it looks like to keep the height under control, trial/error I let them veg too long I realize after the fact.

Sorry guy for sidelining this post, but i thought the followup question would help others possibly.

I agree with this, except make sure your dissection is outside the house and you shower before touching your grow again. These spores are friggin aggressive. Sometimes we can love our plants too much.

Yack i didnt know budworms even exist and those are spreading budrot. Horrible though. Budrot has not spread this day and if tommorow morning look good then im very happy and hopefull. Wife do like the oven bud and i agree it takes the edge off bad day. Getting some early smoke. Sensi skunk looks like it need more time for the trichomes. This like this suck so much but if total catastrophe is avoided i can be happy about the learning experience Moe and all of you guys gave me. This is my 3rd grow and every single grow you learn so much.

If i ever learn to defoliate good enough i believe i have every means to archieve the full potential result of my equiment. I know how buds grow large and healthy, but total air quality, cleaning, and pruning and defoliate must be mastered. I had one perfecr plant first grow big bud 275g dry 0.5m3 space and not coubting the popcorn buds.

Here is photo of my first grow and huge cola with budrot. Its like 150cm tall cola very very thick. 11 weeks flower never change pistil until chop. I love how much flowering sites big bud has and those grow gigantic so you get kinda arm lengh of budding colas.

You got this brother. Setbacks happen, results come with perseverance. You are way further along to producing a clean grow than you think you are probably. And honestly, trimming and primping on plants is actually fun and rewarding for me. I start with an Indica leaner on board (don't want to speed thru this process), put on some yo yo ma, and spend the day with my plants. I have a little shop stool on wheels and just take my time and relax into it. Look at every part of every plant. Check for nanners, bugs, fungus, everything. I address top feeding and recharge media with biologics at the same time.

When done it's instant gratification kinda like how a freshly mowed lawn looks. Plants appreciate the Zen as much as the humans. I've never had a bad day spent with my plants doing normal maint.

Looks like you got plenty of input on this....Im with ppl that are saying keep the RH below 50% in your flower area or have more circulation...Maybe have a fan that blows across plants...
To avoid this myself theres a tiny trick where on those big top colas if your worried about rot?....For 1 always watch for "Dying-off"...
This is when the upper Fan leaves die-off and then would naturally fall off....Where that fan leaf dies is also where the Rot will start as its a death of the node point as this is the latest stage of flower..
So if you see a very yellow leaf and it looks weak late Bloom...Remove it,..,.
Also - Old Skewl huge Cola trick -Pull the Buds AWAY from the Stalk before Rot ensues.....ez..... power to it
Far as what to do with rotted bud...thats your call...
Spicoli/FOE20

ps: on Humidity ...these guys are very correct by saying keep RH under 50%....Look at it like this...
At 51% RH theres still a tiny bit of residual RH to feed mold and rot(this is bad)...at 49% RH the room is Pulling a bit moisture from the area and plants(this is good)...This is the Logic behind it...gl
