Outdoor Sativa Near Harvest?

[sorcerer13]

Hello, I have posted some pictures of my sativa and was wondering, as a first time grower, if it was getting close to harvest.
Have some colas with 50/50 white and brown pistols. I see with my 30x glass and that tricomes look sort of frosty.
Also , what has me guessing is that the buds have swollen calyxes. Is that normal? And these calyxes have no pistols growing out of them.
Thanks
Thanks

Got a few weeks to go based on that pic IMHO. last pic looks like may have been pollinated by something as looks more like seeds in there than swollen calyx's (have to pull one off and see if an immature seed in one of them).

Like Dwight mentioned, Def a ways to go yet on those, and yup you got seeds in that last one for sure!

Few weeks min left before harvests.
Last photo 100% has loads of seeds on that bud. Even the ones in background in last pic have loads of seeds.

Ok, thanks for the info. I wasn't aware that part of the same plant could produce seeds while the other parts are just bud. Am I correct to say that?
