Hi @beecherscoville, good to have you! Say hello here, if you like 
I think you have all the tips you need - my first step would be to check how well the string sits on the tuner peg, as has been mentioned beforehand. Have a look at this video by Fender.
If you got a setup, perhaps call and ask about this. My local music shop has a great technician, so perhaps you can get recommendations to find one around you.
Cheers,
Antonio
