Don't get too anxious. The pics above are only from 3 days ago and they are not going to grow that much in a week. It is too early to transplant and it is too early to start LST. I know it can be hard to wait for them to grow, but it is a trait that you are going to need to develop if you want to grow....just wait until you get to near the end of flowering. It can be almost torture to wait until they are ready. So, slow down, start them on light nutrients, make sure your environment is dialed in, and wait for them to get decent root development before transplanting and let them get some size before you start to do any kind of training.
