Alright everyone here are a few more pics at day 18 of Veg. growth.....I was thinking that these plants are only like 6 in. tall but are becoming really bushy, do you think I could start to flower them whenever I am ready to considering the size of my grow space isn't very big?

In Pic 5 it seems to have been growing only single leaves, but from what i can tell from it it seems to be all one node but there are 4 leaves in diff. direction.....Does anybody know why this could be like that, because this is the only one out of them all to do this!
