I bought a goji plant a week or so ago from a big box store. It was doing fine but I've noticed some of the leaves are turning purple. Does anyone have experience with goji's? There is little I can find about ailments

I snapped a pic to help.

Im not familiar with goji, but I'm thinking transplant shock. Did the plant seem root bound when planted?
If so it could be stressed from the moisture issues, they can dry out quickly this time of year.
My search brought up this-
"Other Causes for a Plant with Purple Leaves
If you have a plant with purple leaves, it may also be due to elevated levels of anthocyanin, which is a purple colored pigment. This pigment builds up when a plant becomes stressed and normal plant functions are interrupted. This problem can be very hard to diagnose as other factors can cause the pigment buildup such as cool temperatures, disease and drought."

A phosphorous deficiency was also mentioned, but I'm leaning toward stress.

It's possible. When I got it, it was kept under a shade cloth where I have it in full sun. I haven't repotted it yet, I'm doing that tomorrow to see if it just a root ball mass issue. I also moved it to the shade to give it a break. I'm not worried about it being dry, we've gotten unusual amounts of rain so I'm more worried about it being water logged. I have it draining now to make sure it isn't too wet. The cool temperatures are also possible because we are just now getting normal temperatures for the time of the year. It's been a cool and damp June for us.

Ahh, I should have gone non mobile to view your location. Sunburn makes sense too.

Just transplant it, keep it watered and maybe shaded during the 1st week, sometimes all the leaves will fall off but new leaves should emerge that are ok with the new enviroment, it has been placed in.
If it has fruits on it pick all of them off. Dont fertilize it either. the weather is crazy here too we got more rain in June (ten+ inches) that Jan,Feb,March, April, and May combined. Yes more precipitation(rain+snow) in one month that 5 combined and we normally get the same amount of rain every month of the year. Maybe the new weather for the NE will be monsoon.

I'm happy to report that after a transplant to a larger container (very mild root bound issue) and moving to a partial shade area, that the goji has returned to its origional colouring, grown about half a foot and started to berry.

Thanks to all who offered advice
