Just keep an eye on em'. The pics are blurry, but I dont see the beginnings of any sex organs yet, make sure they get 12 hours of darkness to trigger the flowering. And look at the secondary growths too for sex organs, plants can show on secondaries before main stem nodes (like 40/60%), so keep that in mind, plus male sex organs can take a week or more to ripen and release pollen(YMMV), so unless you ignore the plants, you won't get pollinated.
The plants look fine, keep it up!
