Hello friend!
D'oh! Looks like yes, you had a herm. It also looks like you have some fox tailing on some of the buds, so that would corroborate with ongoing stress.
You can harvest and consume them, but they'll be less potent and less tasty, not to mention extremely seeded based on your pics.
Check with ILGM directly, but since herms are often caused by stress, I've never heard of any warranties covering herms. They normally just have a germination guarantee.
Hopefully, you kept a journal for your grow so you can prevent the stress from happening on your next run!
