8 week cannibis plants showing signs of flowering under 24/7 light?

Hi there, newb here, (6 years with partner, 2 years solo, so bear with me) I've come across a curious situation and would appreciate any opinions/advice.
I have 8 plants from a friends seeds(a heinz 57 strain, *widow, cinderella 99, northern lights* x *purple kush and island sweet skunk*) and they are currently around 8 weeks old.

6 of the 8 are either not showing gender or just showing tiny claws or calyxes at the nodes--pretty standard stuff from my (somewhat limited)experiance.

However, there are two that are clearly displaying their gender--rather like what I'm used to seeing a few weeks into flower. One is a distinct male with clustered seed pods and one is female with with rather large calyxes and mature, browning pistils at the nodes.

What might could be going on here? Is this normal or could it be the light schedule? I usually start my seedlings on 18 hours of light and 6 hours of dark but I couldn't spare my timer at the time so they ended up under 24 hours of light. (LED veg light)

Just some background info, I received these seeds (already germinated) rather unexpectedly just before a large harvest so I wasnt able to put as much time and attention into them as I normally would. They were normal seeds, not feminised nor autoflower. Humidity sits around 50% temps ranging between 22°C and 28°C. Room is well ventilated. Plants are in soil and receiving 'veg nutes' bi weekly, and other than a minor nitrogen deficiency early on have been otherwise problem free and growing well. All are from the same 'mother.'
Half were topped around there 4th or 5th node, half were not. The more 'mature' ones were both topped.

Any opinions or advice would be greatly appreciated!

Why are these not just preflowers? Am I missing something? Only other thing worth mentioning is that 8 wk plants, in solos, under 24/0 are gonna be stressed af. Weird shit happens then.

Its normal. A mature plant will show its sex during veg. Toss the one with balls (unless you plan on breeding?) keep the female for the flowers.

This is exactly how you sex a plant. Grow it to maturity and you don't need to waste time sexing in the flower room.

Yes, I was quite surprised when I spotted them! Sorry, let me just clarify--the one with the balls and the one with the pistols are NOT the same plant. One plant has only balls and the other plant has only pistils(so far anyway, haha)

Thank you guys for the responses! I dont usually put plants under 24 hour light so I was wondering. Glad the general consensus is normal--a great learning curve though, that's for sure.

Im not sure what you want to know but a plant usually becomes sexually mature at 4 /6 week unless a clone off a sexually mature plant.its rare to see 24 hr light cycle stress, all my veging is24 hr and its never happened in decades, but its a possibility. If your genetics have any ruderalis in tgem thiscan bring on flowering in a veg cycle. Whats happening seems normal one male and a female by the sounds of it

Some strains will flower under 24/7 once they get mature. It's not just Ruderalis that can flower automatically. Everything you are growing is a hybrid so who knows what's in the lineage since names don't really mean anything when there are dozens of breeders calling their strains the same names these days.

Yes, I dont take strain names too seriously--hard to tell what your getting. I soppose I'm just curious why the two plants are showing their gender so strongly while the others are just coming out lol. (Again, I havent done this long enough to be confident yet) That's pretty interesting about the ruderalis not being the only autoflower tho! I guess I'll just have to wait and see what happens with them.
