Noob's first grow ever

And I'm back, my plants survived a month alone with just a drip for irrigation and freezing temps. While I was away the temps dropped a lot, it did snow even thought it rarely does, but I'm kinda grateful because the cold has permitted my plants to survive one entire month without anyone checking on them. So, I already harvested the smallest one, that is now drying before curing, will post an update when I get the dry weight. About the biggest: main cola and higher branches seem ready to me, so I think I'm gonna harvest soon and leave the lowest branches to get some more light. Any suggestion? Do you think she's ready?
