i have these 2 year old JBP seedlings:
Now recently i recognized a discoloration in the needles:
Unfortunately my pine knowledge and experience is very limited so far. So i hope you guys can help me identify the problem. I suppose it is a balance of water and oxygen problem because of the wet conditions the last few weeks but i am not sure. Can anybody support this or does anybody know what causes this discoloration?
Thanks for your help
