This looks to be related to thick, or wet soils. These conditions can suffocate roots. Along with applying copper fungicides according to all label instructions, I would recommend making sure that the top 1 or 2 inches has a chance to dry out, completely, between waterings. If your soil is very thick, you may want to let it dry out even further.
If you cannot let it dry out, you can try digging out a portion of the plant and growing it in container, with good potting mix and compost mixed in.
Too much light can cause this, but the area looks to have some shade, at least.
Lack of humidity will be a concern. This will be mitigated by growing them as a houseplant, and misting them, often.
