What causes this? (odd bud formation late in the grow)

Recently I've had a few instances where late in flower the buds start pushing out new fresh new hairs. I've got three plants (3 different strains) in a tent right now; one is "normal"; one is pushing out a bunch of new hairs but also showing amber trichomes so it's coming down; and one is growing new hairs AND taking on some weird shapes... like its pushing out new calyxes (?) that are popping open with new hairs...

Here's the last one, this is a couple of days shy of 8 weeks and up until recently I would expect this plant would come down within a week, but now it's going all alien on me, I'm not sure what to make of it.

Any thoughts?

Other notes: the strain on this one is LSD (Mazar x Skunk 1) which I've grown outdoors but never indoors before. It was a beautiful plant outside.
 
Whats your canopy temp? Anything over 90 an youll get this. Also your humidity? From the way your leaf looks it may be a little high.

the temps work their way up from 65º (overnight) to 79º for most of lights on. Humidity is between 48-58%. I moved the lights up a bit, it might have just been too intense for them.
 
Thanks, I'm familiar with foxtailing, I can see that I should not have used the word "formation" to describe growth.

The part I don't get is why it would foxtail at the very end of the grow, putting out a ton of fresh new hairs when the plant should be finishing.
My Afgooey did this, I think I let her go too long due to high summer humidity and she was not frosting. Since I pushed time wise I think she started making new calyxes. I learn new things about my strains each time.IMG_5217.jpg because she was not pollinated.
 
Recently I had another plant start to foxtail in week 7, so I backed the lights off and that seems to have made the foxtailing slow or possibly stop. Makes me think the plants have evolved to have fall sun be less intense than summer sun, and when the sun/light stays unnaturally strong until the end of flower, the plant reacts to it. I'm just guessing though.
 
I only get foxtailing towards the end of summer as I battle to keep temps down in my garage. Moving lights a bit higher and adding a second fan oscillating around the canopy seem to help. Overall it doesn't really seem to affect anything except when it comes to trimming. It's a pita to trim around i usually just cut the foxtail tips off into my sugar leaf trim bucket. Also some plants foxtail as they reach maturity and theres nothing you can do about it.

its the plants last efforts before "dying" at the end of the season. its natural and most all strains will do this if they get ran long enough. cheers

Sounds reasonable. I've been growing both indoors and outdoors for a few years, it's something I didn't notice until recently, I guess I just overlooked it before.
