JBP needle tips turning white

[theta]

The tips of the needles on my JBP have been starting to turn white. I dont think its needlecast because I think that appears as stripes on the needle?

I’m starting to alternate each week between spraying daconil and copper fungicide.

Any insight would be helpful thanks.

My guess would be it got too dry and the needles scorched a little or the from the spray routine. Looks healthy otherwise and i wouldnt be concerned. Your new buds look healthy
