I looked up the breeders fb page, and that particular snake you have came from a pairing that was spotnose ghi to spotnose hra. Without a doubt your snake has spotnose in it.
Just a point of clarification, that pairing does not guarantee "without a doubt" that the animal is a Spotnose. There is, for any given offspring, a 1:4 chance of it not having the Spotnose gene.
