Problem- 27 Days into Flowering- Buds hair turning brown?

Its only 27 days flower i am beginning to see a very tiny bit of orange on some of my pistils very very few though i expect at least another 30 days to be completely flowered.... but wait whats that? One of my little popcorn buds pistils turned brown. Im thinking its gonna mold.... Someone have some suggestions i included pics. I just dont understand why it'd do that my temps are around 70-76 with a humidity of about 20-30 and i dont remember squeezing it or getting it wet or anything of the sort. Also tell me how you like my Flouro bagseed grow... thanks!

Plant looks healthy in the pics it is not uncommon for pistils to change color as they age, orange, brown, red, etc. new growth (new white pistils) will take thier place, if you see good new growth I would not worry

Just looks like it got bumped or something like that not to worry.

I agree with riddle. They look good to me. That budsite will be fine. Something looks to have damaged it but its not a big deal. It won't mold with a low humidity so you are in good shape.

Your problem looks very local.I have never had it but it seems like a contact burn with some chemicals but overally they look nice and healthy.changing the pistils color does not happen in local clusters. every small piece of bud begins to change one or more pistill every day.so your problem Doen Not look like that process.

Thanks for the help guys and reassurance i was getting scared thought it could have been damp buds or something. Im actually really happy with these plants at the moment considering my setup and the fact that they are bagseed, i have a lot of stuff on the way at the moment so my next grow should be alot better. I dont have vents though and i cant really make holes in these walls im getting a 250w hps the current temp right now is like 74 day and like 67 night w/ the flouros and the closet is across from my heater so suprisingly it isnt too warm, during the summer it stays cool down there too so i expect the same temps. But when i get the hps I dont know how much it will spike in temp. I have good air circulation just no flow other than a little space under the door where light really cant reach. My room is about 6ft tall and 3x3 what do you guys think? I might go for a cool tube but i don't want to make holes in the walls so i cant vent the cool tube. This is my dilemma. Im thinking make that a veg room and get a tent for my crop but thats alot of work and a shitload more to dish out too.

I've seen it happen when I foliar feed, or spray stuff on the leaves and some flowers get it, turns them that color, didn't cause any problems though.

I have the same issue with the pistils turning brown on 1 or 2 buds. I NEVER foliar feed but I have been getting my CO2 canisters a little close I'm thinking. I use the yeast, sugar CO2 bombs and squeeze the bottles once and a while to see the vapor coming out. I think I got some on the bud, vapor I mean, not liquid. It should be fine though plentyblunts, maybe pick that single bud and dry it! Smoke that shit man!

I wouldnt worry about it as long it still growing and stay green

did you end up figuring out what it was, mine are doing the same thing, bubba kush 20days into flower and the pistols are turning brown, mostly to the tops, and did it end up turning out fine?
