northern lights is a great plant, i suggested lowryder cause ppl on here seem to love it. i havent really grown in, but it seems to meet the qualifications
if u gonna wait, just wait until u get like 8-12 nodes, then sex them. then if u like veg more, after u have determined male/female u can revert back to veg
when you do the bag technique to induce early preflowers (when you cover a branch for 12/12) where does the preflower show up? at the base of only that branch?
