ficus leaf issue after setting outside

Hello!
After setting out my ficus from its indoor grow light table some of my bigger leaves have gotten these dark spots and sometimes they even drop off.
was curious if anyone else has had this happen?
Thanks!

Thoughts??
Anyone?

Sunburn perhaps? May 1st and you already had figs out!?!?
At this rate, where I live, I might be able to put them out for a month......
That's why I'm ditching tropical....

I'd agree with sunburn. Gotta ease those things into full sun after a winter indoors.

Thanks guys.....my tropicals go out when i can be assured that it doesnt go below 50 degrees.
I am thinking of ditching tropicals also!!! well at least fukien teas and starflower due pests almost killing them every winter!!
