Q.Sick Potted Pine Tree
Hello, I have a small potted pine tree that seems to be sick! I am very new to gardening but am trying my best . The needles are brown on the inner branches, there is white patches on the branches (possibly fungus?), the tips of the needles have browned and have white tips , also the soil looks a little odd with white specs resembling sand but i might be just inexperienced ? Desperate to revive this tree and keep it healthy. Any advice would be most appreciated.

If the dots in the soil are moving, it could be soil mites. The bad news is they feed on decaying material, which could be the pine tree. Browning in the center of a pine can indicate root rot. The white could be scale insects. Here is more:
