Top of buds opening

Hello, I'm a first timer at this. My plants are at day 26 of 12/12. Everything looks to be going great up to this point. However, today when I checked on the girls I noticed on one of my plants on almost every bud near the top of the plant there seems to be just one greenish calyx looking thing growing at the top of each bud. A few more developed looking ones have pistols, well what look to be pistols coming out of them. A few even look like they could possibly open at some point. I haven't seen any signs of shemale traits, no light leak, and very little stress throughout the process. This one particular plant is different from the other two which are doing great!!! I have a smaller girl the same strain as the one (AK strain) with the "pods" on the buds, but its very much smaller and shows no signs of this. Can ANY ONE HELP???? Is this just the bud starting to swell, does this happen to all buds near the top, or do I have a problem??? I don't have any pics at the moment, but can try to post some if that will help. Thanks to all.

Does it happen to look like a bannana?

No...I've noticed that over the past few days every bud top, bottom, etc...has this pod like sack forming at the top, and only at the top. A buddy who grows outdoor came over the other day and instantly said they were seeds, but after I pointed out that every bud had this going on he changed his opinion. I'm still not sure what it is, but the buds still look to be doing fine so I'm just going with it for now.

Likely best to provide a photo.

Seeds usually have a lighter greenish-yellowish 'racing stripe' (from it's base, out to it's tip) If this sounds like your calyx's, pluck one off of a lower branch, and check for a seed.
