These look like the start of preflowers to you?

Yes, they will become "pre-flowers". Pre-flowers after only 4/5 weeks with photoperiod plants are usually only associated with male plants, females photoperiod plants don't usually show pre-flowers until 8 weeks or more, or only after changing to 12/12. If they are auto flowering plants, pre-flowers at 4/5 weeks is normal.

Just showing sex. Till you make night at least 12 hours long, no flowering will start with photoperiodic strains ...

Hello mate, they are simply forming the site where the pistills will sprout. Take under control them if you're not sure about the sex but it's very diffucult to see a feminized seed that turns into a male unless the plant undergoes a big stress. Good luck and happy journey!!

Early pre-flowers, yet not showing pistils, but the oval-triangular shape indicate female and not the round ballz of a male! :)

It does look a little early to be sexy in your plants. If you look zoomed in it does resemble a male trait. I would still wait at least a week or two longer to verify if it is a pre-flower or AC pod starting. Just my two cents. Be patient it won't hurt him until it matures more anyhow. So give it time and let it do her thing.

Those are not showing sex yet. I can't remember exactly what the technical term for those are but over all your plant looks super healthy. If it's an autoflower strain most will flower around week 3-4 if it's a photoperiod once you flip the light cycle to 12/12 you should see signs of see in about 2 weeks.
