Interesting leaf colors there for sure, did it rebound? I find that anything coming out of Alaska (I get lot's of these varieties coming though Seattle) tends to throw a freak every now and again, whatever the causality factors are, my guess is genetics.
Usually (with almost everything I do) but especially with things I know come from up North, I try and pop a few choices, that way, many of the weak "freaks" get culled. (sometimes a freak could be a good thing, even possibly yours there who knows, it could have an unusual terpene creating that color) Last thing I did was one of the AK47's and it had sorta a "crinkled" leaf appearance, tried to find the picture, but I can't find it. I tried to grow it out, and see if it "grew out" of the trait, but it didn't. The plant after about a month or more was (somewhat) stunted, I was tight for space at the time, so I culled it.
Overall I would surmise that defects are somewhat more common with Alaska/northern strains, I think the weird sunlight conditions (24 hours sunlight@20-80,000 lumens varying all over the place during that time) might contribute to that issue. Angles of light to the earth's atmosphere creates strange phenomenon) Also, there are many magnetic anomalies and various micro-climate conditions unique to that part of the world. It certainly doesn't seem to affect potency, or viability of the strains, just some tend to throw more freaks than others.
Look at the leaf structure, you can tell she's a freaky deaky.
