Ficus brown spot

[Kelsan23]

I have a tiger bark ficus that has developed brown spots on quite a few of the leaves. The leaves are green but have large brown spots and the leaves can be pulled off very easily.

I’m wondering if it’s some kind of fungal thing, anyone have any insight to this?

I have not had this happen to my tree yet. I hope we figure this out.

It's been outside or freshly moved?

Looks like sunburn.
Has the tree been moved from shade to sun or had more sun through a window recently?
The damaged leaves are permanent damaged and are unlikely to regain green color. The good thing is that ficus are usually bomb proof so it should keep growing new leaves. you can snip off damaged leaves if you like.

my microcarpa also get damage like that and i have put it down to sunburn....

I think most likely sunburn too. I have several with the same discoloration, I keep an eye on them but the rest of the plant seems fine.

Definitely looks like sunburn, it should be fine, next year try to gradually move it to direct sunlight, first a few hours in the morning, and incresase the exposure time every week.

My trees are outside 24/7 and this particular tree along with all my other ficus, stay in full sun and are rarely ever moved unless I’m pruning. I generally check my trees for pest multiple times a week so it’s a relatively new development. Hopefully pruning the affected leaves does the trick.

some of the affected leaves i removed...
only happens on microcarpa and only on a few leaves...

I does look like sun burn, I have had this on new leaves inside the canopy after pruning in summer as the leaves I pruned off where shading the affected leaves and once removed the leaves below get much more light.

I have only had it the way I described above on trees with full dense canopy after a harsh pruning in the hottest months of summer.
