Must have something to do with the strain/genetics/growing conditions etc. Figger an early producing low ryder gonna turn itself to dope in 2 months gonna have to show bud fairly quick I would think. Maybe it take a lot longer for a lanky Sativa. Just guessing of course.
It does depend on genetics.. The more sativa it is, the longer it will likely take.. Will obviously depend on health/vigor too.. I've seen fairly prounced pistils on hybrids 4 days into 12/12 though..
thanks for the help guys! i really appreciate it! because i started to flower a week ago and wasnt sure when the bud would start showing. now i do. thanks again
if your switching your lights from constant 24 hour to 12/12 the sudden dark period will trigger flowering much quicker. you can expect to see most plants sex within a week with this method.
