Are these drying marks?

Didn't know where to post this, so I decided to post here as this section has the most traffic out of the three forum section for film.

Sent my Ilford HP5+ to Triple D for processing and scanning. Saw these white marks after transferring the images to my laptop.

All these three images were taken in consecutive order, and the marks kinda line up. The marks only appeared on these three frames out of the twelve though.

Highly unlikely that it is drying marks as it has nearly the same pattern for all 3 frames at the same place.. Besides, if they were indeed drying marks, you'd be able to see them on the film itself. Why don't you take a closer look at your films to see if there are any sort of similar marks on it? if there isn't.. then its most likely to be the fault of the lab's scanner.. though I also have no idea how it formed such marks.. not exactly too sure what kind of technology they employ..

Yeah the marks only appeared on these three consecutive frames on my film.

Chemical stain/mark.. it happen When film film dip into developer or fixer, and did not stir well. To reduce such problem -
1: pre wash (reduce water surface tension)
2: agitate for the 1st 60 seconds (reduce uneven developing action)
3: use stop bath. (reduce developer/fixer stain, as if fixer ph too high/near exhaust)
hope this will help
