1 plant Closet Grow

First time growing with this set up. Stealth for me is the biggest priority and the only location I was happy with was my bedroom closet, so the only suitable tent I could find was a 60x40x200 (cm) propagation tent. Have never used LED before so this will be a learning experience. The seed popped quickly and sprouted within 3 days. I followed the instructions for the light regarding light height and intensity, however the seedling showed severe stretching which I was able to cover mostly with more medium. Despite stretching toward the light the seedling also shows some signs of light burn however I believe this was from a few days ago when I had the light a lot closer to control the stretching. Given that I only have 1 plant in this space I am planning on LST, which will also be a first for me.
