She looks confused about which way is up. Helmet is off already, so the cotyledon could be collecting sunlight by now.
Does 1.5" seem kinda deep? I been planting them when they have a 1/2" taproot, with the helmet 1/4" below the surface. I usually see movement in a day or 2. I keep a vented dome over it 'til the first set of leaves is out to keep it from drying out (
@420Forever taught me that).
