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!!

Day 8: Spring watered about 300ml each last night; Gonna start feeding sensi grow next watering, also got sensi bloom, bud candy, big bud and bud ignitor. Suggestions on How much feeding and schedule are welcome. Day 9: Cotyledons are yellow on #3 and yellowish on the other two. Dont know whats going on, but researching quickly I´ve read that this is normal behavior, since the real leafs are fine and the plant doesn´t need the cotyledons anymore. Please comment! Day 10: The new dehumidifier is great. Setup on automatic and keeping humidity levels of 55~65. Soil is still moist; Anxious for the first nute feed. Thinking 1ml per 1,5 liter. I got AN Sensi Grow, Sensi Bloom, Bud Candy, Bud Ignitor and Big Bud. Please give me suggestions on schedules! Day 11: Fed them 2ml of both Sensi Grow AB into 1,5l, watered 500ml each plant. pH 6.1, TDS 277, 27oC. Theyre still so little I was expecting growth by now. Day 12 (01/17): Really worried about growth rate/development of the plants. Don´t know if I underwatered or what. Last night with the fed I felt the pots heavy for the first time. Today I lowered the SF2000 light from 32inches to 24inches. Lets hope for response. Please comment.
