In my opinion I would go ahead and wait until they were a bit more stable before flowering so there is no ill effects of light change due to instability in the plant(s). I would give it another 4days - 1week before switching lights. Just my opinion though. This is your grow not mine and your decision is the 1 that matters most. As far as seeds are concerned they could make 20 they could make 2000 it all depends on the plants. As far as breeding (another opinion) I personally wouldn't breed anything I didn't know what it was. I'm growing Ogre and Early Girl and have 1 Ogre male in veg as I know it can't impregnate the ladies in flower. Once I see how the females all turn out and if I so decide to breed I can take a female and reflower her after regeneration and breed the strongest strains I have for seeds (I hand chose which male to breed). Check out my journal when you get a chance it's in my sig on the right. If I decide to breed I will probably make another journal that will show you how to breed and how to select the perfect plants to breed for some great quality seeds. Hope this helps.
