I've known goofs taking their 8 week plants to 12 weeks!! I've known 8 weekers to harvest at 6 weeks.
I found the breeder rec's to be spot on as long as your room/habits are controlled in the same way.
grow to the breeder date, check your trichomes, intake, leaf coloration, pistils, decide then why your plant may not be cloudy milky at that time. ask yourself "Is there an issue I let go? like temps too high? humidity in check? air flow, fresh air supply, c02, did I follow directions with a proven nutrient system? am I using hid lights? 600/1000 watt? - all of which can delay proper finish.
I took this as a challenge and contacted my favorite breeders. Soon my room was equipped and controlled just like theirs...and Bam!! my plants milky clouded during the weeks they said it would most every time.
sometimes a seed pack may show different genotypes, like one being an indica leaning and the other being a sativa for instance. The differences between the two may account for different flowering finish times.[/QUOTE
Thanks for the reply, I figured when the time came I'd be able to tell by the tricomes but might be moving unexpected and was hoping that they would get to finish in time. I'll have to see if they have more breeder info so I can mimic thier grow. Thanks for the help man very appreciated
