No sir. Nothing weak about your stache and soul patch. You are right on target for 6 weeks. They are my favorite part of beards, and many times they don't grow quite as quickly as other parts, but you have fantastic growth. You have a really great look. Everything is growing so well. It goes great with your hair for the total look.

Don't worry about a thing, and don't change anything. You are spot on good for such a short time.  I kind of like your natural neck line when you let it grow also.
