THAT'S more like it!

They look awesome man, nice LST. I thought I'd try to answer your questions.

1. They both look pretty similar as far as the leaf characteristics go... I'd have to say it's more of a indica, while it has some sativa characteristics.
2. You can flower whenever you deem it necessary to. Anyone of us don't really know your setup that you're growing those beauties in. I mean, I can see that it's some kind of drawer, but I don't know how tall it is. Giving us the setup pictures would help determine when to switch over to flowering. But it does seem like you have adequate room for now.
3. They look really healthy man. I doubt I could even give you advice on improving... Do you plan to ScrOG?
