there is a stem, right? and a leaf grows out. between the stem and leaf a new growth grows out then, for example, the top of that is a bud site. the top of the plant is a bud site, unless you topped, then it grew two bud sites. if you watch the top where it looks like new leaves are growing out fast (so fast they look almost like they might be pistils, but nope!), somewhere in there you will notice some of the white hairs, pistils, poking through. this will happen over the next little bit.
i have 2 bag seed and 2 autos. one of the bagseed flowered almost right away, like days. the other i thought it would never! but it did in about 10 days. the autos were auto-ing along, around week 4 but before week 5, they were flowering.
