Spruce tree needles browning
It is difficult for me to positively id the condition from which your spruce is suffering. I suspect a mite infestation, possibly spruce spider mites.

I recommend that you consult a certified arborist to examine your tree, diagnose the problem, and advise you on treatment. Here's a link to locate a certified arborist in your area: https://www.treesaregood.org/findanarborist/findanarborist
