I grew lavender and a plus rock bud back in the day. I had to take soft sand paper to them. The grate you would use on a car running out a scratch / paint transfer.
Also had to sand the master Kush from Dutch passion. The popped pretty good...
Yes.. sometimes this can happen.. and the grower can resolve the issue.
or sometimes seeds get old and are bunk... can be not viable. Can be the seedbanks fault. Not storing them correctly for instance.. and selling really old stock. (just a guess, but my guess is this is a possibility at least with soma seeds strains. have heard this before)
ie: How long have those Alien Genetics LAD f1s been sitting in Bob's desk drawer anyway? Hmmmmmm.
or sometimes things happen in transit on the way to the seedbank and or your house. sit in a hot mail truck all day in the summer and fry to your dismay.
sometimes shit just happens.
I've gotten a ten pack before that was total bunk. 0/10 germ.. got it replaced with the same stock from the same breeder, from the same run.. to get 10/10 germ on the replaements. You just never know sometimes. They're seeds. Anything can happen with these things.
if it were me.. id be taking pictures of the bunk seeds and sending them to the breeder. ask for replacements. if the breeder replaces them, the seeds you get back will be the most fresh.
