Northern Lights in a 2 x 2 (first grow)

At the start of my first proper week of growth she seemed to be doing really well. I noticed her stretching quite a bit, so I moved to the light a bit closer. This seems to have done the trick. Thanks to everyone on Grow Diaries who answered my question about burying some of the stem when transplanting. I decided to move to a slightly bigger pot (from 1litre to 3.8 litres) so that I could bury some of her stretchyness. This was based on advice from you guys - so thank you! She seems to have taken to the transplant well. I made sure the EC and PH of both mediums were very close.
