Smoke from Radiator Cap

Smoke from Radiator Cap
So I was driving and I noticed a bit of smoke coming out of the engine compartment. I opened up the hood, and noticed there are coolant splash spots here and there, nothing crazy.
Smoke comes from the radiator cap and the upper hose. The hose is very good condition, no cracks. The area where the hose clamp is a little moist, but no dripping or bubbling of coolant. The radiator cap was replaced 6 months ago.
I cleaned out all the coolant splash spots. And tried checking for the source of leak and smoke. I let it idle, no coolant was shooting out. However, the same 2 places still gave out smoke.
Reservoir still has coolant. Temperature gauge read below the mid point, like the past 10years. The temp gauage does work, because the needle climbs as engine gets warmer.
So, any advice?

You might have a cold pressurized cooling system leak test performed to identify the leak. Heat may be evaporatinga small leak as fast as it accumulates. There should be some coolant dye stains at the leak location. Probably corrosion/scaleunderneath the hose end fitting is allowing a little coolant seepage.
I replaced a hose on my subaru forester this weekend and cleaned a significant scale accumulation from around the fitting. I could find no fault in the hose, but the leak would lose perhaps 1/2 pt /month of coolant.
good luck
