I was all, "yowtch!" Out loud... I HATE mites...
This looks a bit like mite damage to a ficus.
When you observe those tips closely, are "web-like" areas present?
Get your self a big, white piece of paper, hold this paper underneath the foliage. Then take your index and middle finger, and BIFF drum the ficus, "jiggly-bones"-style..
Observe the paper .... Are there TINY dots?
If so, look REEEEAL close.. are they moving?.
I reeeeally don't believe excess light is the issue here... I toast the HECK outta ficus.(tostando lo mucho).. The leaves are practically TOUCHING my panels...
I believe the culprit to be pest.
Let's touch on some other stuff, while we're here.
What are your room's parameters?.. like temps, RHumidity... Lights AND light CYCLE?
