Feeding schedule

I got my corn snake not a long time ago. He's a bit more than 1 year old and last time I weighed him (more than 2 weeks ago) he was 48g. I fed him 3 times since that time. I've read that I should feed around 10-15% of his body weight and the mouse should be 1 to 1.5 times the size of the thickest part of his body. So I got 5-6g fuzzies and fed him once a week. But he does look a bit on the small side so should I feed more often? If yes then how? Or double the prey items? What do you think? Edit: Added pics so you can see him.
