To answers hush puppy question even tho you answered it already skull is that,
Yes, it could vary in each strain. A more indica from say a cold wet climate / short growing cycle might not take as much "sun" or lumens compared to a tropical sativa with lots of sun and long growing seasons.
Even each plant can be different but I've noticed most plants are the same.
It's similar to a sunburn in humans. To much light and it not only causes growth what looks like "fimming" , topping , etc... Ever pinch some growth off and it grow back all wierd at first b/c you only pulled part of the growth off?
Same looking growth, looks like multiple tops/leaves because the meristem mutates and can't produce nodes so it makes them intermittently all stacked up on each other.
The leaf edges will first roll up on edge first each serreation will be pointed to the light. It progressed to hard ridges on the leaf itself, from vein to vein... Casting shadows across the leaf to "shade" itself.
Then forms "the taco".
Turns to stunting, wavy leaves , small frosty nuggs and wierd growth.
You might not notice all this becaus it can progress in just a few hours from mild to worse and you would never see the signs...
