They are a month and a half you say??? They look a little bit behind, most likely from the light deprivation, well it's the beginning of the summer, and the days are growing longer, so you shouldn't start to see sex until about 2 weeks into fall, i don't think there is too much that you can do to speed it up, you should just let them do there thing, they will catch up eventually, are you using any nutes, if so, what kind??? I'll post a pic or 2 of my previous grow, they are about a month, I just wanna give you something to compare your babies to...
