Coolant leak

I have a pretty bad coolant leak but I'm not too sure where it's coming from. I was driving and saw smoke rolling from under my hood but it wasn't overheating. I finally made it to my gfs and let it sit and idle and was checking under the hood. There is coolant everywhere on the left side of the engine (pass. Side) but still wasn't overheating at idle. I'm going to go check it out a little more in the daylight but if anyone has any ideas to where it might be coming from it would help me pinpoint it. Thanks

Check the freeze plugs, pretty common thing to rot out.

I found the leak. It was a small hose under the throttle body. Is this a return line or something?

No, it's probably the throttle heater line, used to heat it so it doesn't get stuck when it's too cold.
