No, it's not OK.
Is it already wired?
Could be many things, including over watering, under watering, too much heat in the Summer, frost in the Spring.
So, one plan it to put it outside in the shade, create a humidity environment around it, and water carefully.
You didn't show us the pot; is it too small? Have you done a tap root cutting?
Many factors involved here.

All this started after I was away for a week working and home had a lot of unexpected rain. The person watering them did not know to move them undercover and the pots got soaked through and stayed wet for a long time after.

So, overwatering could be the culprit.
Water carefully, let it dry a little between waterings, hope for the best!

overwatering would lead to yellowing of the needles first. ONly after that falling aff / browning.

What did you do the last 6 months?
