Back the temp off a bit - most PLA only needs 160-185 (as the Solidoodle reads 30oC cooler due to its thermistor placement -) - so if the PLA is recommended by the manufacture as a 175-215 melt point, then you want to use 145(which wont work without firmware mods) - 180oC... 190oC risks burning the PLA and causing clogs - as well as it being way to oozey at that temp anyway.
The bed shouldn't need more than 65oC-70oC, even with Kapton + Glass. I print onto a muuuuch thicker ceramic tile, and I still only need 65oC.
Most of my PLA has been done at 165oC in Slic3r.
This will also improve you overhangs - too hot and it will just droop. Colder bed + Colder Extruder will help tremendously with this.
However - for quality PLA printing - I had to resort to adding the fan to the extruder, as PLA is just too runny compared to ABS when melted even to low temps.
So drop the temp on bed and extruder, and see how that goes. With PLA you want to get it as close to the 'low end' of the temp spectrum your particular filament is designed for as possible. If unsure what this is - start at 180oC and keep working backwards. So far I've only seen one particular manufacturers Black PLA require anywhere need 190oC (and it was a clear stand out compared to the others I use). And I suggest you research the fan if you are going to use PLA regularly - you'll just be chasing your tail even with the lower temps you should be using without one.
hope that helps.
