Hey,
I would like to snare with you problem I have with my pre bonsai pinus(mugo and parviflora)
I suspect needle cast But I would be very grateful if someone would confirm that.
Thanks in advance

That is not needlecast.
Looks like overwatering, when the needle's tips get yellow and dry.
Pines need some dryness in the soil between waterings.

That’s very likely, I have it since few days but it had very wet soil. Does overwatering explain that strange curly needles on mugo pine also?

Sorry about the Mugo, I have no experience with Mugos as they don't survive in my climate.
Maybe any other member can help you?

What is the problem? They don't look too bad to me, let them dry out a bit if they hav got wet, otherwise they are fine
