There is a water leak for sure for your windshield washer, otherwise washer water isnt used anywhere. How to find out is the question. Remove the washer bottle by lifting it upwards (usually) go figure out in ur focus. Once bottle is out make it empty and dry and then fill water (outside the car) and test for any minute leak from below. If bottle is clean, then next and only thing to doubt is the washer hose, which tend to get crack as its near the engine heat and start leaking a bit. If thats the case then change those water pipes, its cheap anyways.
About coolant, it should never be consumed firstly. Check visually under the car for green sticky deposit to see from where coolant is seeping. These minute leaks are difficult to trace as you cant find the spot on floor but it deplets when you drive. It has too many things to doubt that first look under the car can get you good starting point. If you cant figure out, drive to enoc pump and mechanic over there can quickly pin point the leaking spot. Just for clue: check the black water hoses joints, check the engine base, check radiator all around, check the coolant expansion bottle and its hoses for leak.
