hmm, doesn't really look like a blizzard to me... I'm not too knowledgable about all the different snow morphs but it looks like one of the many snow morphs.
As mentioned before, the weight is a little problem.
Okay, 8 weeks old sounds a little better but the weight doesn't sound right. Archie what kind of scale are you using to get the 4 grams. It doesn't look like a 4 gram gecko. And it looks good.
On what morph, I would agree with Mari, Mack Snow Murphy Patternless (Mack patty).
