So my weed plants about 3-4 days old each one of the cotyledon leafs curl down no other leafs help please? I only watered once then I mist them and kept humidity levels around 60-70
Without Diary and Info, its hard to say
The "pot" looks bit fishy.. do you have
holes at the bottom of yout pot? cause roots need air
you can see the moisture and it also looks pretty damp
