Hey Growmie,
You're fine my friend Weeks 4-6 buds fatten up. At this stage of flowering, your buds are getting bigger. They'll still have all the white pistils sticking out, but you'll be able to see the buds getting bigger every day. At this point, the “stretch” is about over and you can reduce the amount of training you're doing with your plants.
Hopefully, this was helpful and remember ..."Happy Growing" and "Free your mind one puff at a time".
