Also to clarify are you saying that it does look in fact like light burn or do you still think bud rot?

After what @JadedMarxist said, and the photo i provided ( u confirmed ur plants look exactly like it), its light burn, not bud rot. Thanks Jaded for the info/clarification. It's never good to misdiagnose a deficiency/issue.

Thank you so much for the quick response! You guys have made me a happy grower today :) I was getting prepared for the worst since this is my very first grow and that would've been understandable to be honest. I truly appreciate your help!

Do you measure humidity in your tent? Keep it below 62% to deter mold buds touching other buds may start to mold but is not the cause! Once the plant is got mold its in tje plants blood or systematic meaning that whole plant will eventually rot and can pmspread spores. In that tent depending where in the world you might be and if its indoors or outdoors, but budrot will be rare indoors i that tent with that 1 little fan.

How comfortable is the air in ypur grow space? Indoors hvac should keep humidity in a comfortable range like 40%-65%. Hard to get mold with them numbers

Tug on one of those discolored leaves. If it comes off easily it MIGHT be bud rot. Also, squeeze that top a little. If it feels dry and kinda crispy, then it's probably light burn. If it feels soft and spongy, then it's probably bud rot. The color doesn't look right for bud rot. It looks dry and "bleached out".
If it is bud rot, remove everything, isolate the plant and sterilize your space. The fans could be spreading spores everywhere. As for the plant, you could trash it or just cut a couple of nodes below the affected bud and keep a close eye on it.

That is really good to know. And yes, I monitor both of my tents using a VivoSun G4 with WiFi so when I go camping and stuff I can still see the temps and humidity and call my brother to have him check if something is off. I plan to add cameras inside the tents in the near future.

My humidity is pretty stable throughout the day and night. I rarely use my humidifier and find myself using a dehumidifier more. During the day I average about 40 - 45 humidity (no lights on) and at night I average about 50 - 55 humidity (lights on). I've been very obsessive about checking my app every hour or so for any dangerous changes in the temperature, humidity, or vapor pressure deficit.

Thank you so much for you response. I took some more photos for you so you may decide affirmatively what you believe it is. I left them alone last night and today while taking a video, I noticed the whole back side of the big affected bud has no sign of this discoloration, only the side that faced the light. Could be total coincidence but I also notice what seams like a "bleached" leaf on the same bud where the water leaf looks PURE white. I should also mention that the bud didn't "crunch" when slightly pinched with both fingers or when I gently tried to tug the white water leaf. Notice the right side of the cola has no discoloration, or very little I should say. I apologize for any blurriness, I'm not sure why that's happening in my tents only.

Seconding rootfarmer advice, i'm still not sure from the additonnal photos, bud do look a lot like rotten to me but some leaves looks more like they're dried

"Tug on one of those discolored leaves. If it comes off easily it MIGHT be bud rot. Also, squeeze that top a little. If it feels dry and kinda crispy, then it's probably light burn.

don't hesitate pulling gently to open the bud to see how it look in the inner near the trunk.

I myself think the picture of that bud is bud rot my opinion, like said above pull on one of those brown sugar leafs and if it comes out very easily that's a bad sign.
If it was from lights those other leaves would be taco shaped really bad, just my opinion.

So after inspecting affected area- if I gently tug on the sugar leaves that look bleached white, they do not come off. They bend, flex, but do not crack or tear. As far as pinching the top bud it does give off a dry feeling but it is FAR from soft and spongy. Zero colors of gray anywhere. The entire backside of the cola is unaffected and the affected cola's surface area has not increased so it looks like it hasn't changed from the moment I caught it three days ago. There seems to be no spreading and there is only new green growth. The cola is definitely bigger than it was three days ago but the affected area has not increased in size.

His leaves are taco'ing up and inward which is a sign of light/heat stress. The questions is: how can the buds have rot, if the buds are so hot, it seems its to hot for bud rot. how can you have the two together? it doesnt seem possible being his RH is 50%, temps r high... and hes got 1 fan for circ. maybe bring that fan up from the floor to the roof of the tent for better circulation around the buds.

I was talking about the brown bud in first picture, the bud with the white looking in the bud is from light bleaching being to close to lights

Believe it or not, those are the same bud. It was really hard to get a semi good looking image of the cola. My phone's camera is to blame. For some reason it isn't the best for taking pictures of buds to be honest could be because of the tent and or grow light though.

Mold needs warm and moist air to take hold at 50% i dont think you need to worry about mold. Just sit back and enjoy the show for the next 45 days

It is now five days after my original post and I am happy to say that 1) the discoloration has not spread meaning its 99% not bud rot, 2) its consistency / texture has not changed, 3) the color has not changed, and 4) all of my colas are continuing to grow as they were before. No other buds have been affected and I'll be expecting a decent harvest in about two to three weeks! Thank you everybody for you help :)

First time grower here. To be honest I figured I'd be lucky if I got to even harvest my first attempt so here I am now currently on day 35 of flowering and I have two tents that are in my closet. I've been trying out some of the features with both the VivoSun app and the AC Infinity app and while I was trying to set up automation between one of the apps and my grow light, I had turned on the grow light at full draw ~400 Watt and for some reason my exhaust fan went to zero for about two or three hours and I believe the temps reached about 91 F. I'm not sure how long in those two or three hours it was stuck at 91 F but obviously immediately after discovering this I opened the tent and got all the heat out of there as quick as possible. This was only one of the two tents I should mention- I can't recall which app did this but to be honest it was my own fault.

The next two days went by as usual and I continued my feeding and watering schedule as usual. During my feeding, I decided to take a look at some of the buds because they were getting so huge and I'm constantly mesmerized by the dang plants. In the tent where the high temps occurred for those two or three hours, I noticed that one of the plants, which also happened to be the tallest plant, had an almost orange-purple coloration to it. I wanted to convince myself this was just the natural color coming in because they've been green this entire time and they're supposed to be kind of purplish (Black Runtz) but obviously this was from either the heat and or light stress from being so close to the buds with such huge wattage.

My question to you experts is as you guessed, is this bud rot, mold, or just burnt and if so what specifically should I do with it if anything? As far as burnt buds during flower I've read everything from chop it (the affected cola) for additional redistributed growth (maybe not so much at day 35 of flowering), to leave it alone, to freak out it will turn into bud rot if it's not already.

Please note that my images were taken from an iPhone 13 Pro. Looking at them on my desktop, they look more brown than orange- in person they look orange and purple. The deepest orange is about as orange as the hairs on some of the buds. They don't really look brown. What looks like light brown and dark brown in the image looks like light orange to dark purple. None of the lower buds are affected.

This is the smaller cola on the same plant that was affected. Shows less orange and purple but was obviously from the same affected plant.

This is pretty much what every other plant that wasn't affected looks like. Most of the colas and buds on the affected plants still look normal, like I said it was just the higher colas and only the tops of them affected.

View attachment 2327308

Of my eight plants, only two of them have a weird color like this, and it is ONLY at the top of the colas that were near the over powered lights. These two plants were in the same tent where the exhaust was off for two to three hours. The two other plants in this tent were not as tall as the affected plants by about 6 - 8 inches in height and are just as green as they were before. I noticed the affected buds yesterday when I turned the lights on which was about two days after the event occurred. Yesterday the strange colors on the affected buds appeared as orange-purple.

What should I do you guys?

Bud rot. Just had the same thing on a half dozen tops .
It just gets worse and bigger the longer it goes.
I did trim a couple pieces within my reach to give me a couple more days of feeling good.
Enjoy and good luck.

I posted this topic about six days ago, if you read through the thread you'll see that a couple other members already helped me diagnose what the issue was and it was not bud rot. It was a mixture of light burn / bleaching and poor ventilation (for about three hours). I posted yesterday, exactly five days after my initial post regarding the discoloration and have conclusively determined that this was not bud rot. After seven days 1) the discoloration has not spread meaning its 99% not bud rot, 2) its consistency / texture has not changed, 3) the color has not changed, and 4) all of my colas are continuing to grow as they were before. No other buds have been affected and I'll be expecting a decent harvest in about two to three weeks!

No crunchy crunchy, no grey discoloration, no fuzz, no funky smell and its been five days. I think it's safe to say I'm in the clear. Furthermore, I have taken a look at the affected bud and the discoloration only appears on the area that was directly affected by light. After gently prying the bud open I was surprised to see everything was a healthy green color.
