Thanks for your question.  The tree is a true fir, looks like grand fir.  I am not sure why the needles are turning up, could be herbicide drift, like 2,4-D?  Might be heat stress if in a warm, exposed site. Tree growth looks good and otherwise the tree looks healthy.  I would suggest watering well this time this time of year, deep watering periodically (every couple of weeks) and perhaps applying a little nitrogen fertilizer after you get some fall rain.If there is heavy grass around the tree remove a 3-4 foot area around the tree to reduce competition for moisture.
