breeders give general time frames and with seeds its hard to predict exactly. each seed will vary quite a bit sometimes. its important to check the trichomes for the most accurate way to tell when your plants are ready.
but with these pistils still like this, i would say shes about halfway done. you have atleast 2 more weeks.
a good general rule is that buds will fill the space that the pistils reach too and if you chopped now, youd lose potency and overall yield.
she looks good and like shes gonna fill out to give you some nice chonkers but she still needs quite a bit of time.
with the breeders recommendations, alot of the time they fib a bit on how long it will take and in some environments, what they say could be true.
for instance, a plant in hydroponics is know to grow faster and bigger and if the breeders only test or grow that way, then it may end up different for you.
environment and cultivator can also dictate the length. if you did everything exactly right, you may finish in the 70 days.
but its very unrealistic to predict that everysingle seed will finish in the same exact amount of time especially autoflowers. the genetics are constantly changing because they cant keep parent or mother plants around for long term stabilization.
but that and environment has caused you to have a longer flowering phenotype. phenotype is genotype+environment.
even if we both had the same exact clone, we would get different results because of our different environments, medium(soils, coco etc) and our different feeding regiments and lighting. so many variables ontop of the unpredictability of using seeds.
each seed is really its own thing and no seed will ever be the same. theyll have similiaritys but thats why people keep special clones around for 20+years. they know theyll never find that specific plant again, even in 1000 seeds.
