Pal
That's an auto.
I've looked at your diary.
She will start to throw out pollen sacs. The rod method.
You leave plants flowering way over their given cycle and they naturally give out pollen sacs
That was done weeks ago pal.
Idk if the leaves have just come to their end of life. Most likely. If I didn't know b it was flowering so long, I'd say its serious bud rot. But, buds look good bit, ya you're right. Them bits of green. Are signs she's starting to prep herself to produce sacs of pollen.
Ppl do this to get pollen from plants. And that's how you make fem seeds. As the pollen collected can be added to new seeds in pre fower making your own strain..
Those leaves dying in such a way, is all signs she's prepping herself for
