Lopsided

Sometimes it can happens when the light repartition is not equal , most of the times it happens in the corners of the grow box so it is good to rotate the pots from 1/4 every weeks or X periods. In your case it will be fine

Yes sir the only way you can actually tell what it is.. Is when it starts to develop flowers and gets some odour/look to it and even then it's really hard to look at a bud and "know" what strain it is.

Sometimes thats just how they grow. Maybe your light is closer to one side or the other causing the side that isnt as close to stretch a little. I wouldnt worry about it. As far as info on the plant goes, unfortunately no obes going to really be able to twll you much about it if you dont know what the genetics are. We can comment on how its growing and issues you have, but strain, yield, growth patterns, etc. are gonna be unknown.
