What are those strange looking balls with 1 filament/pistil?

Those are calyxes, same things that plump up around pistils that make up buds. You know it's a female if it has the whispy white projection. They'll show in vege, if given enough time. I wouldn't recommend doing this, but when those things are all plump and crystalized, they'd pack a good bowl for sure long before any buds are ripe in bloom. (not vege).. don't mutilate your plant like that in bloom, but it would be stoney.

Salut le jardinier ! Un pistil ou 2 ça indique quand même une femelle tant que tu a pas de fleur mâle tout va bien. Les pistils s'oxydent avec l'âge et finissent tous marron à un moment donné. A part l'âge les pistils deviennent marron pour pleins de raisons comme trop d'humidité ou de l'eau qui tombe directement dessus ou même trop de vent. Bonne chance bella ciao

Hi! The balls with hairs are called calyx and if im not mistaken when the calyx gets pollinated the other pistil goes inside the calyx and they change color. Stress and touching can also do the same but if I were you I would check for some balls if there is some pollen somewhere..
