Hey there, bro! Yeah, that's pollination. The stigma bends when it finds pollen, thus pollinating the calyxes with trichomes. There's already a seed in one of the calyxes. No big deal, bro! Just keep an eye out for random pollination; pollen can be on your clothes and hands, and such cases can happen when working with the plant. 👌
But there's a chance that another plant, a male, is growing somewhere nearby. You might search for it for a long time and not find it; their pollen is very airborne, and no one is immune to this. 👌
