Are my pedals greased correctly?
From your description yes, your pedals sounds to be not greased properly.
If you please could post a photo from different angles, it would be easier to provide further advice.

In general, if there is a possibility of disassembling, you should do this and repack the bearings, the same way as you would do with cone hub.

For temporary solution or if the pedals cannot be disassembled in non-destructive way, a thin grease or even chain lube may be suitable, but then the pedals should be greased as often as you lube your chain.
