Sexing regular seeds: flip to 12/12 then flip back to veg?

I've never grown regs, but now have a bunch that were gifted to me.

SO, can I flip them at maybe 2 weeks veg, and then flip them back to veg 2 weeks later (or whenever they show female pistils)?

Downsides? Any advice would be greatly appreciated!

Flipping them to 12/12 that young can cause problems. Most of the time it stunts them and they have to mature a few more weeks before they will show sex . That being said some strains will take off on you and start stretching and showing sex in a few days.

It might be easier to take a clone from each plant...label the plant and its clone as you go...once the clones root you can put them into flower...keep them going or toss them once you determined the sex(es).
This way the main plant keeps vegging and won't take weeks to re-veg if its put into flower.

That's one way to do it. I know that space quickly becomes an issue in my grows. So I veg in 64oz plastic cups from the gas stations. I had a partner sprout 120 seeds in solo cups one time of different bag seeds and some store bought seeds mixed in there. We had our hands full but it was a great learning experience. When it was time to re-pot them I had to take a bunch of them and just flowered out about 30 of them and most of them didn't respond well to going 12/12. But there was a few that would be great for a sog grow. All in all it was a pain in the ass and clones and fem seeds are definitely the way to go.
When it comes to re/veg some strains will go back and forth easily and some strains never really recover. Its really not worth messing with if time is of the essence.

They won't show sex until they are mature. So switching and switching back gives you no information if the plants aren't mature enough. Just keep an eye on them for pre-sex.

Easiest way that I've found is grow the plants, clone and lable both clone and mother. Flip the clones and trash the males after sex shows.

I was told told to do a 4 day flip but only after sexual maturity and then toss the males and reveg the rest.

Lots of solutions to an age old issue.

Why would you bother to do a flip if they demonstrated sexual maturity? Further 4 days won't give you the auxin shift you need for sex determination.
