first thing you need perlite. second it's a bit stretched. third you should never partially water a plant. it can cause the roots to turn back upward in search of water. when watering, wait till the soil is almost completely dry then water thouroughly until you get a bit of runnoff out the bottom. finally it looks like your plant is a polyploid strain which just means it has more than 2 growth tips at the nodes. ice from nivana is such a strain.

my advice is to use perite when you repot, also bury the stem to the coytldons(spelling). and try to get the lights a bit closer.
