5 days isn't very long, the others should figure it out soon. If you used a multispore syringe then it could be a genetic reason for the variable fruiting times. That's a fat looking little pin ya got there in the first pic, I hope it grows well for ya!

Fruiting prior to proper colonization (beyond what meets the eye, internally) certainly may be partially to blame, and as another poster mentioned, genetics are a variable, as well as each individual jars conditions, inoculation points and quantities, and the quantity of spores per injection site.
