Laughing Buddha/first time growing

hey,paid those girls a visit today,they are doing really good! One thing to note is that there is a difference between them in the way they grow,one of them is short and bushy and the other tall,i thought the bushy one was just left behind her sister but thats far from the truth,she just grows differently. Whats up witht that barneys? Am i getting a 100% sativa and a mixed one here? Did perform some lst for them,nothing ground breaking,i am just trying to get more light to the auxilaries growing underneath. The yellowing on the leaves stopped so i gave them some more of the bio bizz bio grow. Must have been a nute burn to be honest,never making that mistake again. There is a weak but pleasant smell coming from them,like a really fresh and pungent spice,almost peppery :P i dont think ill update soon,see you next time and a happy new year growers.
