2nd grow let's see if I learned anything

Starting off 3 seeds but only going to grow one of them to maturity. They are in plastic cups with a hole in the bottom on a boot mat to catch water runoff. Starting them off in the coco coir with RO water + Calimagic only. So far an unknown breeder Northern Lights Auto that I got from North Atlantic seed company seems to be in the lead above the two Colorado cookies seeds. North Atlantic didn't know who the breeder was either, I guess they get their freebies in bulk. In the pictures NL is up top and the CC seeds are the bottom two. I don't think the middle CC seed is going to make it as a seedling despite germinating. If the NL auto still looks better after a week I will stick with her and kill the other two because I'm only doing one plant this time given the size of my tent - but I am increasing the pot from 3 gallons to 5 gallons to hopefully encourage it to grow larger since only one plant. Will transfer the winning seedling from the cup to the 5 gallon pot a little after a week passes. In addition to going with only one plant instead of two super cramped plants and the 3->5 gallon pot change, I also intend on doing more LST and more effective trimming of fan leaves this time around. The temperature is increasing here in Arizona so I will be less dependent on a space heater.... just need to wrap things up before the temperature really goes high with the desert summer!
