Ok. Let me help with the LST if I may. You should really wait until the plants have a few (5 or 6) sets of leaves until you LST. The reason is - the point of LST is to get the lower sets of leaves to turn into growth shoots and grow to the same level as the main growth tip so that you have an even layer of growth tips. If you tie down a seedling with only the top two leaves, there is nothing under the first set of leaves to grow even with the main growth tip and #2 you are taking away the plants ability to grow as the only leaves performing photosynthesis are the tops - which are now pulled over. So please - untie them and wait a little while!
