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: 
And the leaves just kept dying.
Today I decided to just harvest it. Here it is after cleaning: 
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?
Can work but really big risk of mold. At least of you got bigger buds. And I rather have to dry than to moist. Hang them or wetcut flowers and put them on a net . Dehumidifier is good to use. There are cheap moist controls you can put in the jars afterwards, same they use for cigars well worth it to not have to worry to much about missing burping them.
I sort of described the method I was taught inaccurately, I meant to put in jars for curing after it was already hang dried most of the way through with a fan also, this was in a lower humidity locale though, for sure you'll probably want a bit more moisture control in a more humid place
