Acacia keeps getting yellow

[nutboi]

I keep getting yellowing on my rabbit ear acacia, these photos are mild, I've had it much more severe. The yellowed twigs come off with a very light pluck.

I can't tell if I'm over or under watering? It's very dry here and I generally water it once a day. Usually the top inch of soil Is dry by next day. I mist it about 5x a week as well.

could it also be temperature related if it's getting down to about 45f at night and back to 80f during the day?

I have the same thing happening this time of the year with a couple of my Robinias. I don't have a solution, just want to point out that these are compound leaves. The yellow "twigs" that come off are leaf petioles. So it's the equivalent of a single leaf turning yellow and falling off on a tree with simple leaves.

western high rockies sounds freezing...
my acacias yellow a lot and it normally seems to be sun scorch or under watering...
It isn't anything to be too concerned about - just part of their makeup...
Your tree looks healthy.
