First Grow! Gorilla Glue Auto

First ever grow. [ Gorilla Glue Auto from BSF Seeds ] Germination: Seeds gone to the cup with spring water ph 6,5 on day 12/31 for 18 hours, then to the wet paptowel on 01/01; #1 and #2 cracked next day with half inch tail, the #3 would let another day sit on papertowel. #1 and #2 gone to medium (Mix 50% Turf, 30% Perlite, 20% Coco, PH 6,5) on day 01/02, and #3 on day 01/03; Sprayed with spring water ph 6,7 with about 100ml each 7 liter airpot; Day 1: #1 and #2 sprouted next day 01/04, #3 only came up a day later 01/05; (That´s the day that starts to count as DAY1?) Day 4: Watered again on day 01/08 around 200ml each with spring water ph6,7 (*Mistake??* Was dry only on the top I´m guessing now...) Day 5: I keep thinking they´re going too slow. I would love auto experts to chime in and give me some tips and feedbacks, I just feel unsure, and have a lot to learn. Day 6: Pics added. Why taking so long for other sets of leafes 2 come?! Entering end of week and still bugs me that this isnt going as fast as I wish. When comparing to other diaries from similar strain and I see much bigger plants by the end of week 1 gets me wondering... Day 7: Very little growth comparing my anxious expactations... #3 has some yellowing on the cotyledons and the 3 of them were kinda dry a couple of inches or more, so I´ve watered it Spring pH 6,7 250ml each as a ring around it. Comments and tips please be welcome. I´m really glad for your help! Ordered a good desumidifier today as recommendation of you my fellow friends for ajusting humidity levels. Thanks!!
