To flower or not to flower?

I wouldn't yet they far to small im surprised how many people turn there plants so small I wait till at least 6 weeks and plants look like proper big plants they still look tiny I would wait at least 3 more weeks but upto you really the yield will be reduced alot at the size they are lucky to get a oz a plants

I would go at least 6 weeks. Your plant will flower but yield will be greatly reduced.

I don't even think of flipping until the plants have at least 5-7 nodes and then I apply some judgement based on the variety and size. Yours, I would wait longer but take my advice with a grain of salt. I tend to grow fewer, larger plants instead of packing them in like you are doing.

No I don’t think it’s time to flower yet. You just got into the veg stage. Germination and seedling stage is about three weeks. Once your plants have three to four sets of leaves, then the vegetation stage can begin. Your plants haven’t even shown their sex yet. Until the growth starts getting offset she’s not ready to flower. Flipping to 12/12 too early isn’t good for a plant either. Your plants probably could use a bigger pot at this point and about an other 3-4 weeks of veg and then flip to 12/12. That’s my two cents for whatever it’s worth. Good luck 🤙
