The calyxes are the buds. Buds are just clusters of calyxes with pistols coming out of them for the pollen to land on. With smokeable buds you're seeing calyxes coated with trichomes and dead pistils. Seriously grab some bud from your stash and you'll see a calyx with pistils coming out of them.
You can sort of see how the buds are put together by looking at male pollen sacks. Pollen sacks grow off of their own stems
but with females the density and number of flowers are greater.
Right now you are waiting for the calyxes to multiply and swell.
