Could be a little brown algae ?

Thanks.

I's not all over, just at the tips of the plant. I mean that all the needles
at the end of the plant are brown, not that all needles have brown tips. The
needles are rather sparse in some places too. It almost looks like a burn or
a lack of nutrients. But I have plenty of Nitrates.

If you can't be kind,
at least have the decency to be vague.
