Default Den. normal leaf drop or pests?
I re-potted this Den. a few weeks ago. The new cane appears normal and the other older cane is also going thru the normal leaf drop. I can't say it's sunburn because it's currently in my living room.

Those spots appear to be fungal or bacterial infections.
Do the leaves stay wet indoors?

No, and I make sure the leaves don't get wet when I water them. Can I spray the leaves with Physan 20? I don't have any fungicide.

Thanks,

Physan is fine. That is definitely fungal.

I think it needs a good spraying to make sure it doesn't spread.

Cheers,

Is there any air movement around the plant, as stagnant air can also cause fungal problems.

It might even be a better idea to remove the infected leaves and then spray the plant to ensure there is no further infection as a few leaves lost is better than the whole plant.

Cheers
