This is only like my fifth grow I think, so I'll be the first to say I'm a newbie-but I've never noticed the flowers on tobacco to bloom pure white and then slowly over the course of a day and a half to two days turn pink before. Granted I wasn't looking for it but if you guys go out and check your fresh bloomed buds are they doing that too? I could have swore in years past they were pink upon opening.
I've topped every last plant and only have one variety in bloom right now though.
