Female or male?

Very early female calyx forming, no doubt about it. Not a hermaphrodite and not a male.

From the images I would say you should see pistols anytime. It looks like it's a female in the early stages in my opinion.

Kinda looks like a new leaf emerging in the new photos. I don't think its showing sex yet. At least to me its not. You asked this same question with different pictures less then 24hrs ago. When I said it needs more time. I was referencing to a few days to a week. not a few hours lol. growdiaries.com/grow-questions/68750-ist-das-normal Good Luck!

"... a hairy white hair" -- missed the "y".

I don't see a stigma (pistil / hair). when they are this premature, you can remove one, split it open and use a magnifying glass or digital scope to inspect for a white hair -- stigma are very distincly different from anthers. You will see the hairs inside fairly early before they pop out of the calyx. Look at any macro of a pistil. It's a hair white hair.. https://www.dinafem.org/uploads/estigmas_macro.jpg Anthers look nothign like this. There will be 2 hairs in a female calyx. There will be several anthers (nanners) in a pollen sac. https://2fast4buds.com/temp/img_upload/bg_14309220535eccf6f205989148137dd1.jpg -- couldn't find a good image, but imagine those 2 anthers (nanners) but smaller and packed inside a pod. take a preflower off, dissect it. Inspect with magnification. You will know several days sooner this way.. or, wait until it is more obvious with the human eye. male preflowers will eventually be more than "1" .. it'll be multiple sacs forming vs 1 or 2 calyx per node (2 if you still have symetrical growth, 1 if it is old enough to exhibit asymetrical growth patterns). Female preflowers will definitely show a white hair. These observations can be made with human eyes long before any pollen is produced. So, there's no need for dissection, but if you want to remove a male plant ASAP to reduce your own efforts, dissection will be the fastest way to identify a male plant - excluding lab testing which we mostly don't have at home, lol.

Wie alt ist denn die Pflanze? Vorblüte..? Im Auge behalten und warten. Um das 100% bestimmen zu können dauert es ja nicht mehr lange sofern du schon die Blütephase eingeleitet hast. Gruß ausm hohen Norden und viel Erfolg.

weiblich

Female. If it was showing male traits they would look like a sac or ball on a little stem, that grows a little out and hangs down. The formation of the sacs is always the dead give away. Plus there won't be any pistils comming out of the sac.

female

bit too early to be absolutely sure but I'd be leaning towards a female mate
