They look very small for 30 days old. We need more info about your grow to help you out. Medium, nutes, environment? The more info you give us the better we can help.
First time grower, my chronic cough condition as created some issues. Unfortunately swelling in my leg turned out to be fractured, I've been in bed. 7 weeks trying to have caregivers and random friends looking after these seedlings until today, I am released from bed rest!
I use organic slow-release nutes, Earth Dust. . I think I really screwed up germination by leaving cling wrap atop their solo cups. Of the 10 seeds I germinating 9 pops they are still alive . The stems we're weak to start out stunted. Having that cellophane ceiling on their cups with a major f******.
Furthermore I think I screwed up using a Coco coir medium rather than a sphagnum peat moss Wood Products Medium as directed by TGSC. I am also thinking that Medium may have dried out and lost some of its vitality. Amanda medium in February periodically watering as needed, it may have desiccated third possibility is the biology is DED dead. :-(
