: 1) Why did the plant seem to remain with only 3 blades per leaf, long
: after reverting from flowering cycle - would it ever have changed back
: to 5?
that's a genetic question requiring controlled studies.
: Much more importantly:
:: 2) Is it possible to regenerate the original strain, either through
: reciprocal crosses and then subsequently producing an f2 generation by
: crossing daughter plants (with use of giberillic acid), or any other method?
you'll need the an original NLxSkunk1 plant to start. every generation
must be cros bred with NLxS until the undesirable traits are bred out.
Put it this way: if you crossed your NLxSxKush with NLxS 100 times (yes,
100 plants) maybe 1 or 2 of them will have the right genetics your
looking for. otherwise you'll have to wait 2-8 generations to get what
your looking for.
your best chance is save time, spend the money at Sensi or HempBC or some
other seed co.
just grow it and grow it and grow it.
