Why is this limber pine drooping and can it be saved? I planted 3 of the same limber pines this spring and have been monitoring watering by checking the soil and only watering when it is dry. The site is full sun, on a slope & soil is sandy loam. 2 of the 3 trees are doing good but one is continually droopy on new growth. Needles are browning out in the center.

Thank for for writing.
Take a careful look at the tree for sign of white plne blister rust and send me photos. The signs are here. https://extension.umn.edu/plant-diseases/white-pine-blister-rust

Thanks Steve! Attached are some more photos of potential problem areas. I am not sure if these are indicators of WPBR based off of the images on the site. There is Ribes near by, however they currently do not show symptoms.
Thank you for the photos.
The picture on the right shows a canker where the dead needles are ..https://www.fs.fed.us/rm/pubs_int/int_rn406.pdf
There are multiple blackened areas https://pdfs.semanticscholar.org/b9c5/12a811f6acc4c458b938b89427fd54d01f77.pdf
It also show rusty spots which are seen in the middle picture as well.
I suggest that you have an arborist evaluate this tree and the others and suggest management. https://extension.umn.edu/planting-and-growing-guides/how-hire-tree-care-professional
