Advice Welcome - First Grow

Week 1 Germination was.. something. Had originally bought two strains, Northern Lights and Wedding Gelato (From RQS). I only intend growing two plants at the moment, but I started by moistening up a paper-towel, then wrapping it around the seeds. I them between two plates, in a semi-warm location. I started with two seeds from each strain, so that I had a backup, but neither of the Wedding Gelato's popped. I think I was a bit too eager, and disturbed the seeds by checking too often. In any case, maybe a blessing in disguise that one strain didn't pop, as I've come to know that it's a beginner mistake to try to grow two strains at once, if you're not prepared to do so. I intended to grow one of each plant, but I am not left with two Northen Lights which is the strain I had the most interest in anyways. One seed took a bit longer than the other to emerge from the soil, so right now that plant is slightly smaller. I do have labels to keep track of which plant is which, and how often I'm watering / feeding. I haven't added any nutrients yet, included schedule says to start at week 2, and I'll be starting at half strength. It's been very humid, which I think the seedlings like, but also very hot, which I don't think they like. Luckily, nothing extreme. Temperatures should start getting colder, and I'll be getting a dehumidifier soon enough.
