ILGM sweet mix (autoflower)

Germination: Started germination on the 5/18. I germinated 2 gelato auto seeds, 1 zkittles and 1 weeding cake in separate mason jars. By the 20th one gelato and zkittles showed their tap roots. The other gelato and wedding cake were cracked but not a definite tap root was shown. I did some research and read that seeds should of opened roughly after 12 hours so i switched to the paper towel method and saw rapid germination after that. I left for the weekend returning on Saturday and noticed the gelato and zkittles that showed their tap root first were growing way quicker than the weeding cake and gelato #2. their tap root was about an inch long while the other two was less than a half inch. Saturday: I decided to go ahead and plant the seeds on Saturday to be able to start the week on Monday and keep track of my timeline with ease. I planted the Gelato and zkittles in 5 g pots while the two slower germinating seeds ( weeding cake, Gelato #2) i went and put in 2 g pots. i was worried some of the seeds wouldn't sprout so i said what the heck lets throw them in some smaller pots Sunday: After work i came back to check the seedlings to notice the zkittles and gelato #1 was already at the top of the soil zkittles looked healthy but gelato to me looked a little darker and seemed sad.... i dont know if i did anything wrong by watering too much, maybe too much light idk its my very first grow so i was micro managing a little too much for my liking. The weeding cake and gelato #2 was still below the soil. i believe its because when i planted the other two the tap root were so much longer than the ones in the 2 g pots.
