I can see some Budrots too, its been rain past few weeks in every evening about 1-2 hrs, in South Asia climate guys, good sun light and buds smell nice

Sometimes you can control rot by just removing the affected areas if you need to give them more time, but it's usually an ongoing problem once it starts. You're going to get to a point where you'll decide it's "done enough" to save from any more losses. Outdoor growing in my area has similar issues with fall rains and trying to finish a harvest before they begin. I try to stick more to fast finishing indicas, I live too far north to really do a good sativa run outdoors. Even then though, sometimes those rains come early. You can try to cover them with some type of awning to help protect from rain, though just high humidity is enough to set off rot.

If your plants have rotten buds, they need to be cut off as quickly as possible before the rot spreads. As for the maturity of the plants, only a visual inspection of the trichomes in the buds can answer your question. And without any photos, it's complicated... :3
