<span class="link_user">@GrowerEugene</span>, I'm not exactly an authority on photoperiods (as this is my first try) and I never did mainlining before so i don't know how that affects the plant....But your Dark Phoenix look like a lovely and big enough girl, so my guess is go with it growmie, if your not sure and your not in a hurry than there is no harm in giving her a week of vege more.
Blessings to you brother Eugene to your beautiful gardener and your wise decisions that you inevitably gonna make....Bles, Bles, Bles :bouquet::bouquet::bouquet:
