Any ideas what this could be????

Second indoor grow here, first one is on 3rd week of lowering (Ortega Indica). This is a Big Bang feminised seed, started her in water, than between 2 plates, nice root came out in 2 days. In her goes the dirt, organic waste composted, soil, sand, perlite, some manure in bottom of 10 litre bucket. She is kept in a closet lit by 4 26watt cfls (various range 6500k, 4000k, 2700k.) Emerged from soil pretty quick, by the time I came home from work, the seed shell was gone, with one of the cotelydons...... She is 12 days old today, and the tiny leaves are curled, and V shaped. Temperature is 16-25 C degrees. Any ideas???? Watered her twice with plain rain water. Is it the loss of the cotelydon? Any nutes missing? Too much heat? Too much light? Thanx

Genetic mutant.

Looks like a crap seed. That medium is also crap and hasn't helped, there's weeds and leaves and shit in there encouraging gnats, spidermites and diseases.
