I would like to know too, I have couple plants that have same kind of spots. I could not find any insect either, even took off one leave & tried to disect it to see if there is anything living there...no luck.

I have no idea what it is, have never seen it before. The leaves still look otherwise OK tho'.

Perhaps Noki, if you could wait more than one day for a response. It's a weekend after all, people do have lives & lots of other things to do.

I have had a couple spots like that one my Thanksgiving Cactus since right before Christmas. They don't seem to be spreading or hurting the plant. Wish I had some answers as to what it is though...

Watering foliage of some plants (like the one in pic) will leave small droplets of water on leaves even misting can cause the foliage to slightly burn. Think of water droplets turning into a magnifying glass on the leaves then when returned to lighting leaving the marks that are seen.

Best case is to water INTO the top of potting at soil line or bottom watering. If the mix is right(bottom watering) it'll absorb the water when applied.

The burn marks you have now will be there for some time(2 - 3 years) they will slow down new growth and may interrupt the anticipated seasonal flowering. Wait for crisp good new growth of three segments if planing to collect cuttings.

Totally makes sense mrlike2u! Thanks :-)
