Im wondering why some plants at day 3 look like mi...

All great points, every grow is different, as well as every strain is different. I recently realized that some of my seedlings took off and immediately began growing, while others were slow and took much more tlc and problem solving. If you've gotten a decent light setup as well as soil, etc. I bet she will pick up for you. Those first few weeks can be frustrating getting everything sorted out, however if your ph is good, your heat reasonable( 80 could be a tad high), and you're not over or under watering, I feel confidant the grow will pick up. I definitely agree with stick as checking the light specifics, many leds claim to be much more than they are. Good luck with your grow, I'm fascinated by the space bucket approach.
