Are these pollen sacs? On fem autos

[WITC]

Have found them on 3 out of 4 plants all autos? And all strains that I’ve grown before also

Yes

Dang. I found them on all the ones that are in full on flower do you two think to much fan pressure blowing on them can cause that? I’ve already bagged them all up ( threw them in the trash) but they they were some some of the prettiest plants that I’ve grown? I’m sure that it’s pretty much just a guessing game? The only other thing I can think of the temps at night get down to 64or 65at the lowest. Only 2 of 6 didn’t have any sacs on them. And the ones that had sacs also had nanners.
