end of the hose, is this bad? 2005 Highlander
43,000 miles

I opened my hood today to add some windshield washer fluid and I noticed that my coolant level was exactly on the "L" level. I also noticed some dried up coolant at the end of the hose that goes towards the radiator. The coolant level seems to stay the same when I checked it this morning and when I checked it when I came home. When I look in the coolant reservoir it is yellow on the top. Other than filling up the reservoir a bit does anyone have any other suggestions, should I be worried?
