Hey Stashio,
Did you put your lamps higher a few days/ one week ago?
When you do that, your buds will stretch and make fox tails.
But in other cases, its just genetics.
Another thing, when you have high temperatures your buds like to stretch and getting fluffy as well,
if you want compact buds, lower your temperature a bit.
27 degrees is just fine but you can do 24-25 as well.
Good luck growing :)
