What is wrong here? Please reply!

This looks like a pretty picture, but not a very pretty site? Notice all of the dark purple growth? What does this mean? Is it bad to the point where i have to worry about the plant dying off? I saw it in this plant when it was much smaller but then it went away and now it seems to be back again? I'm going to start it on blooming ferts w/in the next week or so. Its outdoors, obviously! Thanks for any replies! I just want to know whats up if its a serious problem or not?

The big pic is the pic of the plant as a whole. Thanks let me know how i'm doing...!

very strange, does it seem to be harming the plant or stunting its growth? if not, just wait it out. it may be a genetic trait.
