It looks like it's to early to tell. Zoom in on the nodes and post another pic. If there are little wispy hairs - female. little sacs - male

Could be too early, but Is that some signs of the plant starting to bud at the bottom of pics 2 and 3? If so I'd say it's a female..other than that, it's kind of hard to tell..take pics closer to the stem.

All phenos are different I'm sure.
Mine vegged for 5 weeks,
and didn't show pistols till a week and a half after the 12/12/ switch.

auto-flowers will flower within your normal veg hours (18/6 or 20/4 or 24/0) ...so no need to switch to 12/12, but you can if you are concerned they may not be auto-flowers

If you really really really want to know you can force sex them by going 12/12 then when they show bring them back to 18/6. Otherwise, just wait and they will eventually show.
