Spyder7answered grow question 5 years ago Your plant looks fine to me. Two sets of true leaves with no drooping or signs of light stress/burn is a good week and a half. I'm a few days behind you with my second grow of Early Miss, also from CKS. I'm on day 8 and the second pair has of true leaves, which you have now, have only just begun to come out today though there's not much there yet, beyond the tips of them. Your plant is about where I expect mine to be in a couple days (I'm also growing in soil).
My plant is also short: 3" so far, after 8 days since it popped up from the ground. I think you're doing fine. Nice plant.
