Yes it depends on the strain. There are genetics, that doesn´t show sex at growth (or you cannot identify it, because presex flowers are too unspecified).At 31 days, should they not be showing sex yet? All my other plants were showing sex at around 3 weeks or so. Is it just the strain. Thanks so much.

A lot of times males won't show sex until they've been in a 12/12 light cycle for a week or two. Females are much more likely to show a pre-flower with a pistil in Veg. Be careful you aren't sexing plants based on 'undifferentiated primordia'. These are pre-flowers that are neither male or female. A lot of people make this mistake, confuse a primordia with a male flower and cull it when the sex actually hasn't shown. There's entire threads on this subject, my opinion is that there's no easy way. It's mostly experience. Male flowers tend to form in clusters and look like 'balls'. While undifferentiated primordia are usually by themselves and have a more triangular shape. You should definitely look at some pictures online and familiarize yourself with the different look. And be wary of anyone who says there's an easy method or trick to distinguish between the two.
Growing outdoors, every year in late May and June I'm driving myself crazy, inspecting pre-flowers trying to get my plants sexed early. I think there's a genetic aspect of it, some strains i'll have most of the females separated by the middle of June. I've also had a plant keep throwing primordia until early August, then finally show a female flower. It's frustrating. Now you can order sex test kits for around $8 a plant, you can get it all figured out when your plants are a week or two old. All this new tech is taking all the fun out of growing..
One more thing i should add. If I start my outdoor plants in late March, by the end of July they're 120 days old! And still not sexed. Usually they show in late May to mid June, that's 60 days or more. Indoors is different but still, if your plants are throwing female hairs at 30 days your lucky. I'd be very suspicious that a male flower on a plant 30 days old is an undifferentiated primorida and the true sex of the plant is still to be determined.
Question:
Since I'm just breeding anyways, can I put the seedlings that are a month old in 12/12 now? Pros? Cons?
If you mean you are just going to let them pollenate each other with no selection you can just throw them into flower together. If you want mostly seedless, or want to do a selection, or cross specific plants, this isn't the way to go.

Because you want to preserve the old genetics, do 12/12 and do then an open pollination (best way to keep genetically variety). You´ll harvest many seeds. Next time bring out some seeds and do a selection run with them..
