Newbie at Large

The Abacus CBD was a bag seed I started about 6 days earlier. Its looking very good. All but one germinated and had one that looks stunted. It's one of the autos, will wait to pull it since I still have room. This is the part I like about growing the least, waiting for the roots to take hold and get some growth going. So far so good. Light is raised up all the way in the tent and I have the pots on an upside-down bin to raise it closer to the light. I feel like the light should be closer but dont want to shock them either. Currently running 50% power probably 2 to 3 feet away. They seem to be doing fine so I will keep it as is until they mature a little. Any suggestions are always welcome. Thanks for looking.
