If the gaps aren't too wide or long you can make up a spackle of micro-balloons (white), sawdust from the planking you are using and un-thickened epoxy. I would recommend testing this on some scrap and letting dry completely to check color variation. You will use more sawdust than micro-balloons for color matching. To apply, mask the deck planks just scant of the edge (not more than a 16th) and apply spackle with a putty knife. Allow to set up completely and feather sand before finishing the deck.
