It could be several things. The lower radiator hose connects to an elbow that houses the thermostat. So, you could have a leak coming from the hose itself, the connection the hose makes to the elbow could be leaking or it's leaking where the elbow connects to the block.
From what I understand, there's coolant lines going to the engine oil cooler on the driver side behind the alternator. You could have a leak there.
You'd have to remove the timing cover to see if it's leaking from the water pump.
Wherever you see coolant forming a drip, look above that area and see if it's leaking down from a higher spot or coming right from where you see the drip. Maybe you could hook up a cooling system pressure tester and see if that makes the leak more prevalent so you can find it easier.
This one is supposedly a very good pressure tester recommended by many on this forum:
