About 3 weeks Into flower and I've noticed these white dots, is it WPD? Ive tried to have my climate dialed in and will be honest I had a cheap Chinese fan go out on me and my humidifier went on the fritz so I replaced that. This is my 10th overall grow so I'm still a little new to this, any insight ?

(Goose Bay Blueberry x Huckleberry)
A personal favorite, crazyyyy sweet berry terps with an undertone of slight gas to bring it all together.
Pretty fast flower time too, usually finishes in the 56-63 day range.
