I am a big noob but I had a similar case, my guess is that the root is around herselft and mine died about 2 weeks after germinating, not much I could have done.
Maybe try your luck with another one, 1 month is too long for a filure, get busy and keep that one until it die, at least you tried.
Sorry to see this. I thought was just me. How many did you pop? Out my 10 pack all of them died off early except one that came out the soil with two heads. She’s flowering now but other than her they either didn’t germ or died off early like where yours is. Didn’t like water didn’t like dry.
@rooted Was my second attempt. The first never popped……
