The stalk's purpling. It looks like phosphorous deficiency.

That last picture of the fanleaf looks sort of like a potassium deficiency in the making. I don't know what kind of medium you're using, or what fertilizers you may or may not have given, or if you tested the pH of the soil and/or runoff.

Could you elaborate?
