What flow rate are you using?

Where can I check it? Cura or printer?

It's called flow and should be under material in Cura. I think that it's should be vissble by default otherwise you might have to enable it. If you can't find it open cura, put you cursor next to any setting, you should then see a cog wheel pressing that opens a window where you can search for flow and then enable it. It should then be visible under the normal settings. Flow is basically how mush material is going out of the Nozzle. You could try increasing it and see if it makes a difference.

At the moment it's set at 100%, maybe I can try increasing to 200?

You might look to see if your extruded is calibrated correctly. Tell the extruded to send 100mm of material and see how much is used.
This is a good idea! It may be hard with a non Bowden setup but what I would do is to put a piece of tape or similar on the filament roughly 200mm before the filament enters the extruder. Then follow this tutorial
A 30 cm or so from the inlet of the extruded, touch a magic marker to the filament. Measure the distance accurately. Extrude 100 mm. Measure again. Tape could work. If you have a magic marker, it’s probably easier.
