AsNoriuanswered grow question 2 days ago Plant looks like underwatered , despite wrinkle reminds more of overwatering . Humidity guess is wrong too.
Leaves should never touch soil, they cant evaporate and sweat then, lift them up . Maybe you should start lst a bit later ...
Maybe i see magnesium issues starting too.
Rethink what you do.
Colour bad, structure bad, even metal holders either rip roots or attracts extra cold during night time, so i would never use them ....
