alright my knowledge of botany and cannabis aside....remember this post?

not necessarily your lack of understanding the production of thc and other compounds within the vesicle etc and well im sure ill get to that after your next response
that would seem to go over your head.
anecdotal evidence would ALSO suggest nothing is changing.. to expand on what has been said, i can grow a landrace sativa (love em) if i put it on 12/12 from seed it will not flower until it's "mature"
There are three physiologicaldevelopments that must occur in order for "flowering" to take place: firstly, the plant must pass from sexual immaturity into a sexually mature state (i.e. a transition towards flowering); secondly, thetransformation of the apical meristem function from a vegetative meristem into a floral meristem or inflorescence, this is all visible once you can see sex appear on the plant.. An external stimulus is then required in order to trigger the differentiation of the meristem into a flower. This stimulus will activate mitotic cell division in the meristem, particularly on its sides where new primordia are formed. This same stimulus will also cause the meristem to follow adevelopmental pattern that will lead to the floral growth..bud begins to form
ill try and keep it simple.
so now that the plant is old enough it begins to flower and form buds. this formation is the same on an 8 month old plant,
the buds off that harvest will be the same, say i like that landrace from seed and i choose to leave some foliage after harvest and reveg ie i decrease darkness below the critical night length (back to 18/6 or whatever) and veg for another 2 years. there are no developmental changes and the bud is just as good. this is known by any grower who has done 12/12 from seed to burn through stock and select mothers...,
back to my quote, thc production
thc is produced...
inside the trichomes
Geranyl pyrophosphate and a precursor to olivetolic acid react, a c12 (for pentyl) c10(for propyl)polyketide,then through cyclization yielding olivetolic acid..
then catalyzed by an enzyme to produce cannabigerolic acid along with alkylation .. The production of Thc (and propyl)thcv cbd cbdv and cbc cbcv are controlled by 3 different enzymes Thca synthase being the enzyme converting cbga to thca through an oxidative cyclization of the geranyl group on cbga(of course this is all a bit, well really simplified for y'all) geranyldiphosphate + olivetolate =cannabigerolate + diphosphate.. cannabigerolate + O(2) = Delta(9)-tetrahydrocannabinolate + H(2)O(2)
these precursors and enzymes can be altered slightly through environmental factors say through uv and the corresponding photoreceptor (uvr8 )
but overall this is predetermined by genetics in the seed.. age of the plant WILL NOT affect what the individual trichome is doing, they are formed on the bud which forms during flower in both cases
