I suspect that my Norfolk tree is lacking humidity. I have started to vaporise it but I have noticed blackish spots ( see pictures). This is a nice, tall, more than 10 feet high tree, acquired 2 years ago by the previous house owner. It's been loosing needles and turning yellowish , especially in the past 3 weeks.
I was wondering if the black spots could be a disease. From research, I have found anthracnose although I'm not sure how it looks like on a coniferous. I wouldn't want to aggravate the problem with increasing humidity if it looks like fungus. What are your thoughts on this?
Thank you soo much, it would be very sad to loose it. Sorry, english is not my mother tongue

Your NIP is not diseased. Please post a photo that shows the entire plant and its pot so we can better evaluate it.

It does not require increased humidity as long as it is watered properly.

How far is it from the nearest window?

I have cleaned most of the bad branches a few days ago. It's been in the same spot for over 4 years although the previous owner of the house kept the house cooler since they only visited during weekends. It's been 2 years for us. That is why I thought that more heating has made the atmosphere a bit too dry...

The head is a bit tilted since we had to move it 2 years a go to repaint the floors and the tree wasn't 100% straight during that time, I didn't think it would be affected that quickly but the bent remained.
There are in fact 3 trunks
Because of the size, it is almost impossible to think about repoting it..
Thanks you very much!

That is a beautiful tree that has been well cared for. It does well in cool, but not freezing temperatures. It is unusual that it has not lost more of the lower branches Thumbs up . I see one that has lost some of its needles and can be pruned off.

It is not diseased and I am not sure why you suspect it is.

The only problem is height. The tallest stem is already at the ceiling and will only continue to grow taller and push against the ceiling. If you prune off the top growing tip of any stem, that stem will stop growing and may very slowly die back over the course of several years.

The bend is because it grows toward the light.

Don't even think about repotting it!

There are in fact 3 trunks so it is the smaller trees that makes it look like there are lower branches! I will continue to vaporise it once in a while since you don't think it looks like a fungus. When you zoomed the pictures, you can see dark areas either on some the needles and/or branches. For exemple on pic 2, there are some at end of the dried needles.

Thanks for you help, it is much appreciated!

The fact that the younger, shorter stems are retaining their branches is a significant accomplishment. I don't believe there is any indication of a fungus problem. I also don't think the vaporizing provides any significant benefit, but it is also harmless.
