lst works well, i use it all the time, i have used to to make a plant grow side ways and thats what i did with my last grow, with this grow im just doing lst to the branches to stop them growing up and make them grow out a bit first so the light gets in and these branches grow out from the plant a bit, this should give more yield, looking at the plant in the right picture you see the 2 big fan leaves, not the very top fan leaves that are slightly smaller but you see that big one that is 2 shades of green the one looking directly at us, well if it was me id remove that leaf and the one on the other side at the same part of the plant, this should then let loads of light into the plant where the nodes are, not having the light getting in will mean it wont grow, either that or pull the leaves out the way using pipe cleaners.
here is what i do with pipe cleaners
1, poke a load of holes all around the top of the pot,
2, now you have all these holes you can poke a pipe cleaner through it and put it on the stem you want to move, then hook it over that stem or leaf and then pull the pipe cleaner back through the whole so it pulls the leaf or branch out the way, then this will keep them out the way and should get loads of light in, i find pipe cleaners are easy to use as you can bend them in any way you like and re-use them,
if you get the chance to get the plant out in the sun then id do that as cfls dont throw the light very far so the sun will help and get it growing loads, keep the cfls as close as you can, try and open the plant up to get the light in else you will have no branches to growing, i had this problem with 1 plant and after some lst i got it growing and when the branches got some leaves in the light they started growing quick then,
