Toasted Blackjack - Light Toxicity?

[taijoo]

Had a (Nirvana) Blackjack go all toasted on her seventh week of flower:

It seemed like the plant became light-sensitive and just, well, kinda toasted itself. It burnt from the top-down, so it doesn't seem like a nutritional deficiency. It was exposed to the same light as the other girls (the ones on the left are the same age, the ones on the right a month or so younger), so it alone just decided to self-immolate. The other Blackjacks in the same crop are doing quite nicely - in fact, they're fricking monsters.

Anyways, I chopped her down way early.

...smokes just fine!...

Yeah, I tried to diagnose bud rot, but it didn't seem to fit. The buds were fine, healthy inside, but just went all brown and crispy on the outer layer. The roots seemed healthy. I couldn't figure it out.

Here's one of her sister Blackjacks at week 8 of flowering. She's turning into one of those, "How many more yo-yo's ya got?" producers.
