I could switch to flower but should I???

Hey hey! Deez blunts back for some specific queries.
I’m in the barber shop now so pics have to wait.
so I’m in week 6-7 of veg. My plants are supposed to be all the same genetics. There are non feminized photoperiod seeds out my bags of weed. They were planted on the same night, but are all looking very different. It’s been the same batch from my guy so it should all be Legend OG. I have one that’s nice and tall. It’s began to show asymmetric branches but I’m not sure if it’s officially showing sex. Maybe I can’t find the “pussy”lolsmh Def no balls tho. Then I got the other big one that is much fatter, leaves and all. She’s not as tall and not asymmetrical yet. Then the small girl is.. small. A runt by comparison to the others. She’s just a short bush I want to reach the size the others are in some way. Legit she might only be 8in tall.

You could flip them and see what happens, sometimes the small bushes take off. Take some clones before flipping if you can.

The problem with bagseeds is you don't know if they came from a female that got pollinated by a male, or if it was a herm that pollinated itself or what. Unless you find nanners in the bud you get the seeds from. So watch out for herms. As for them being different sizes, you can slow the bigger ones down by topping or bending branches to let the others catch up and even out. If you are week 6-7 veg they should display preflowers any day now if not already. It's ultimately up to you when to flip into flower. I like to max out the space and get the most out of the light being used. So if you're using a small light and/or small space then it might be time.
