Excessive stringing and deposits on surface

When I print multiple objects or objects that cause the tip to travel I have this extreme stringing between parts. There are also these deposits that'll build up on the sides where the hotend returns to that object.


My settings:
Material: PLA
Print Temp: 185c
First Layer Temp: 195c
Retraction: 1mm (was higher but it jam on prints with a lot of retractions or creates bubbles on the surface)
Retraction Speed: 60

The hotend is a Mark V and oozes quite a bit from the tip.

Any help is appreciated.

Edit:
It's possible my thermister is wrong, For some reason it display room temperature (~65-75 degrees Fahrenheit) as 0c but the temperature does actually change with heat.

If it displays 0 degrees at room temp, then one would assume that it will heat up way beyond extrusion temp (and cause stringing?). Check you have the correct thermistor set in firmware and also check the resistance of the thermistor at the plug (disconnected) to measure its ohmic value.

When I measure it with my meter set to 200k (Every setting it has is in 2's) and I got infinite resistance. At 2000k I got 388


Edit: Changed the thermistor setting in Marlin as a 200k sensor which gave me 14c as a room temperature. I borrowed my gecko's thermostat which told me my room was 20-21c so that's much closer!

Sounds like a new thermo would be a good move.

Yep that's the plan. I'm wanting to get a whole new hotend altogether since this one is a cheap knockoff that I fell for buying before knowing better. I'm just hoping to do some printing till then.
