Only 2 weeks of vegetative?

thank you for the quick answers guys, like using 14 l pots, so I don't think it's a matter of pots, but it never happened to me that a little girl flowered so early

Check out my grow of grizzly purple kush auto preflower was at about 2 week where I added bud blood and bud igniter it’s like a photo plant that starts to show before you change the lights I give 50/50 grow /bloom nutes from preflower to about 3 weeks from that point it’s chewing thru nitrogen for the stretch that’s when you get your best growth . Anyways my grizzly judging on amounts of space that it’s taking on my racks it’s at about half pound

5 liter is pretty small. I run my auto's in 3 gallon pots. I have not seen pot size trigger flowering. I've mostly grown in 3 gal pots, I've run northern lights and gorilla glue autos from growers choice and both started flower in week 5. On the other hand my herz og autos I have growing now started flower after 21 days. I would use bigger pots if I were you, but when the plants start flowering has way more to do with breeder and genetics. Once a plant starts to flower, it will almost double in size before it starts sending all its energy into bud production. Also just because a plant may be a little small doesn't mean it won't have a good yield. Happy growing!

Ehat is the pot size some fenos start reallly young, and she is gonna strech a lot but seems you have it on 5liter pot if soo is a small pot for an auto
