These pics are not close enough... do you have pistils at terminal? preflowers?
some autos are not "autos" due to contamination of the wrong pollen or just bad breeding practices. 9 weeks is an awful long time and borderline point where you simply just assume it is a photoperiod.
BUT, if you see pistils at terminals, it's in flower.
as far as teh stretching you mention in diary, as long as you are giving 35-40 DLI, it's probably just normal stretching for that strain. some are lanky by default, some are not. Greater variety in genetics when you work with autoflower strains.
