Funny smell after primary fermentation

So a funny smell has evolved in my IPA... When fermentation first started it smelled so good and now that primary fermentation has come close to ending the smell has changed a lot and not in a good way compared to what it smelled like at the beginning. Is it normal for the smell of the beer to change that much? Could this just be the beer settling it self out? Will it go back to having it's fresh floral smell once I dry hop?

Here is my recipe:

Briess Golden light dry extract 4 lbs
Coopers amber LME 3.3 lbs
Briess 2 row caramel 40 1 lbs
Briess 2 row carapils 1 lbs
Centennial pellets 1oz 60min
Citra pellets 1oz 30min
Citra pellets 1oz 10min
Citra pellets 1 oz dry

Wyeast labs American ale 1056

It's been fermenting at 70 degrees for 7 days now.

Can you expound on what type of smell you are getting?

Its almost a musky smell... Its not a terrible smell but its not what it was when it started. It almost smells like a coors light which is a weird description I know but I would much rather my beer smell like an IPA then a coors...
