Bad news bro, no signs of flower, it's ready to flower but no signs of flower , probably a photo which was mislabeled by the seedbank or the breeder. Bad news : you'll need to switch to flower. I will say though just because you're in 12/12 doesn't mean a seedling will suddenly flower , after all there is such a thing as a technique called 12/12 from seed - so.switch away when you feel comfortable. This plant is looking healthy and showing preflowers meaning it's ready to flower . Great first grow actually : every grow has some sort of issue and yours has this random pretty rare issue but you're doing a great job growing so... That's a plus ! Hope this helps ! š
