New Grower When to Flower?

[flowerpower17]

I have a non auto that's on day 34 of veg I'm just curious when non auto's start showing their sex, I don't see any male or female parts on the plant? Also It's currently on 18/6 time schedule when should I switch over to 12/12?

The strain is Iced Widow

Some strains will shiw if you veg them long enough but not all and they could be BEASTS by then. Ya gotta go 12/12 with ur lights and most will show ya their private parts a couple weeks after that.

Should I go 12/12 now at this point or wait and if im waiting how much longer 18/6?

Ive run photos on 12/12 from start to keep them alittle small and cut down on power but it doesnt flower any earlier than if you veg it for a few weeks then put them to flower.
