Answers:    they necessitate both sun and water. like their cousins tomatos, eggplants and tobacco plants.(Also the (gasp) Deadly Nightshade.) Add a tiny bit of Miracle Gro too.
Good luck! They're one of my favorite plants.
Could be too much fertilizer, especially nitrogen. This would promote energetic foliage growth but would slow down flowering. I can see buds on them, so they are going to bloom any day now. Maybe contained by the morning.
