It can happen from a fan blowing directly on them or if you fertilize with too strong of nutrients. It could also be from other types of stress like deep staking the root zone in flower or from training too late. Dont stress, just try to figure out which of the above things it could be.

I had some super red/orange tips almost at the very beginning of flower/pistil development. But it was only a few here or there. Under 5 bud points affected. 4 weeks later, flowering full force ahead with great bud development. How far into 12/12 are you?

I have been in 12/12 for 21 days and i'm gonna turn down my fan also not give any nutes for a while. Also one plant lost a significant amount of leaves from the bottom from nute burn but it has no orange hairs. This is my first grow but it has been going good until this stuff.

What kind of nutes, amounts? You should flush if burn or overfeeding is an issue. but if those red hairs don't progress (atleast too rapidly) I wouldn't be too concerned. You could stress your plant more by trying to figure/adjust for this problem. keep a close eye and stay on course!
