Is this chock loss in donor zone 2 weeks post FUE hair transplant? (Photo)

It is not uncommon to have some hair loss(effluvium) in the donor zone after harvesting for FUE,however it is usually more diffuse.This may be secondary to overharvesting but hopefully the hair will grow back.It will take 3-6 months to see if growth resumes.

It is best to follow up with your surgeon if you are having issues.  It may be shock loss but it may also be something totally different.  You need a proper exam for a definite diagnosis. 

Yes, it is shock loss. It happens occasionally even in well executed FUE as a result of the unavoidable trauma from the extraction wounding process, inflammatory factors and cytokines are released which can cause shock loss. This can be minimized by using smaller punches as well as by spacing out extraction points more widely. The good news, is that this phenomenon is typically temporary and should resolve within 3- 6 months. Using minoxidil topically in the area may hasten the recovery of hair

Without a proper examination it's impossible to say over the internet, but it probably is shock loss. This means it's temporary, and those hairs should regrow back over the next few months. It's just a matter of waiting for the hair to regrow. Shock loss generally happens because the scalp is put under a lot of stress in a hair transplant, causing it to drop the hair.

 There may be sometimes such a early phase alopecia, bald spots  in donor areas after FUE surgery,  but fortunatelly most are transient. İt may happen because of over harvesting or transient post traumatic shedding /shock loss. Any way it heals and hair regrow in 4-5 months of hair restoration surgery .

You question is a good one. You have vascular compromise of your donor area from the FUE. This is more and more common as more FUEs are done world-wide. I wrote about this before, see below
