odd question about perflower

iv got 12 plants in a dwc system in my closet, 4 @ 3 weeks, 4 @ 2 weeks, and 4 @ 1 week. my question is the ones that are 3 weeks old ( from seed) are about 5-6" tall and are starting to show preflowers even though the lights are on 24/7, is this normal, and can i keep growing them in veg mode with out them continueing to flower??

What type of stains are they?Some plants do show preflowers early in the game and some even flower when the lights are long,it's genetics.

could be an auto flowering strain, my diesel lowryder pre flowered at 3 to 4 weeks under 24 hrs light

I have seen many plants show preflowers early its not a big deal just saves you some time and space knowing early what is male and Female. My buddies mama plants showed preflowers really early at about the same time and they are mamas and they are still veging strong. They are just covered in preflowers at every node. Horny little buggers

not sure on strain, they are bag seeds. but that would make scence as they came out a bag of deisel. so i should just wait it out and see what happens?

Y not? Y not wait to bake? lol. KEEP STEAMIN!!
