Hi everyone,

This is my first post and I have been looking around the site for an answer but I cannot seem to find one.

This week I have noticed strange spots forming on all my bedroom plants, in different ways. Do you think this might be caused by a bug???

1. Chinese Money Plant (Pilea peperomioides):
As seen on the picture a couple of leaves are showing indentation on the edge (very suspicious shape, like someone munched on them). Only 3 leaves are showing indents in the entire plant so quite sporadic.

2. Lipstick plant (Aeschynanthus Japhrolepis):
Silver spots appeared on the leaves (I would say about 10 leaves on the entire plant). At closer examination I realised they were not spots but kind of some watery bubbles underneath the plant's skin (like the green was sucked out in these spots).

3. Ficus Benjamina:
Only three leaves are showing these brown dry spots on a 1meter high bushy Ficus, so again very sporadic.

4. Devil's Ivy (Epipremnum aureum):
2-3 leaves are showing holes.

5. String of Hearts (Ceropegia woodii):
I noticed 4-5 leaves had these little holes at the back.

6. Polka Dot Begonia (Begonia maculata):
This plant is the most damaged. The damage started about 1.5 month ago and I thought it was just sun damage or water chemicals. After switching to distilled water and keeping that plant in indirect light, the spots continued to appear and are now everywhere on the plant.

I spent half a day inspecting the plants thoroughly but can't find traces of bugs.

Any ideas what might have caused these?

Cheers,
Ben

I can't see any insects either. I see a couple with tiny white specks that are very hard to see. But I do not see any solid evidence that there are insects.
I do not see evidence of spider mites, no scale, no armored scales, no aphids, no mealybugs, nothing.
Sorry I am of no help. Perhaps others will be able to diagnose the issues.

Did the climate in your house suddenly and drastically change? Because I can't believe a bug or disease would affect all these different plant types almost simultaneously...It's a toughie

There has. been a wave of sun and heat two weeks ago here with a 10 degree difference but not too drastic. Went from 13 degree cloudy to 19 degree sunny for a week. Could it just be it?

No Ben, that temperature change is not it. Those temperatures are reflective of what happened outside, not inside!
Your house didn't change 6 degrees Celsius, did it? Unless the heat was off and the windows and doors were open.

Nope, I maintain a level of humidity and temp all of them were happy with. Both Lipstick and Heart String plants start to flower so I don't think they have suffered a shock. I'll inspect some more...

I see no evidence of pests or diseases. Many of the symptoms are normal blemishes and others may be due to some physical damage and still others caused by improper light or watering or mishandling during repotting.

For the most part, none of it looks serious. Serious problems are better diagnosed by examing the entire plant, not just a few leaves.
