Hello Astrid,

I will. I just thought that I was dealing with same thing and just kinda wanted some opinions or poll on next step of action. It seems like the same as I watched the video and everything that was stated in it is the same. I am sorry and didn't mean to hijack your thread
By the way have you found a solution to this problem? Cause inquiring minds would like to know, LOL.
Again my apologies. Have a wonderful weekend.

It's okay! I hope I didn't come off too grumpy, but it's almost always better to start a new post, I think. :)

I don't consider the leaf spots to be a problem, really. They are (in my opinion) just little blisters on the leaves that cause only minor cosmetic issues and do not harm the plant. So there's nothing to do but to wait for old leaves to be shed and new leaves to come along, and enjoy the flowers in between.

Let me ask this of you. The spots that your seeing are they surrounded by a halo. It was hard for me to see. Did they look like the pics that I have taken of my plants? The reason I ask is on some of mine the number seems to grow while others don't have any of those spots.

I mean, the spots on my plants' leaves do have a little "halo" around them where it looks like the leaf is more transparent.

But for me, the bumps are raised and have some texture, and are impossible to remove without really hurting the leaf (think: picking them off with a needle).

I have heard that other things the black spots might be include a minor fungal or bacterial infection, small sunburns, and so on. It could also be scale insect, but those are definitely raised bumps on a leaf and should be easily removed with alcohol. I think it's often really hard to say.

I think you should keep an eye on the plant. If the problem spreads or you start to notice insects or something, you may figure out what it is. I would keep it away from other plants until you know what is wrong.

Ok I was just trying to pick your brain a little. I didn't think it was scale and tried those methods I even pulled out the razor knife to try to pop off the caps make it easier to remove but that didn't work that actually it ended up destroying the leaf. And these to, are raised little bumps and they do seem like they grow in number on one of my plants it seem to increase and has since died off a little.I don't know if it was the conditions or what so I was just picking your brain.
The plant you see in the pictures is not even with my collection inside the house, it's actually one I keep outside, and is new to the collection altogether about a week old. So I will let you go and again on my apologies, have a good weekend
