hey dont take it personal, im sure it will be great... however i have some 20 week sativas that have nice full colas at 12 weeks. so your looking at low light levels slowing maturation or a deficiency doing the samt thing. if its not any of that then that plant will take forever and you should just chop.
it will be fine big plant big pot rare pheno
not taking it personal
just on here and other forums
its automatically assumed that your doing something wrong if your plants run longer been growing strictly auto's for years now and have seen major increases in size and potency
but with anything new there is still a pheno swing until it is further stabilized
ive grown with the same setup and yes ive grown out lots and lots and lots of airy buds
but ive got my run times down on most the strains i grow
i looked for threads to compare to but have found few that actually look like my plant but they say its the monster pheno
if this one wasnt topped and lst'd it would be close to if not right at 3'
thats alot different from my 18" 1 oz'rs im used to popping
