Update on trying to grow cannabis

Only two of a buch of seeds that sprouted ended up surviving. One started flowering pretty early on, despite getting the exact amount and schedule of light as the other one (they shared a pot). The other kept growing taller then died without any signs of flowers.

The post pic is from ~2 weeks ago. At the start of this week, it looked like this:

I don't know what strain this is, because I didnt label the seeds. But it smells very citrusy and I know there were some lemon haze and lemon skunk seeds among them.

What are the next steps? I've heard I should hang them somewhere to dry, is that correct?
