You are correct with your watering but be sure your medium is well draining (add perlite when in doubt). Also - and this is important - your Plumeria will go dormant in the winter and will not need any water at all during this time. It will signal its dormancy by dropping all the leaves after which you can stop watering.
Personally I like a timed release fertilizer so I only have to apply it a few times a year.....
