Autoflowers don't necessarily mean they are boom done in 8 weeks total. Autoflower means it doesn't require a photo period change to switch into flower. This looks like she has just switched into flower and the journey has just begun! I would start feeding bloom nutrients and let her run her cycle. The flowers in your picture are not even close to mature so nothing to worry about! You look like you've got a lot of good bud sights. Let her keep going. I am on week 6 on my autoflowers and some have bigger flowers, some still have small flowers.
Now if it has been at this stage for 6 weeks with no growth, I'd cut my losses, but if you are on Week 6, nothing to worry about.
