I need help with my Calidoras please. :(

A month ago I brought my 2 Calidoras upstairs and started watering them, getting them growing for summer. They're coming along nicely but when I got up this morning, I found little spots on their leaves, some of which have turned into little holes. I've looked them over closely and can find no bugs anywhere. From day 1 I have been giving them Miracle Grow every couple weeks.

Does anyone know what the problem could be?? I'm quite fond of my Calidoras and would appreciate any help you can give. I'll post a photo or two.

Here is another.....

Glenda,

Those spots don't look like you have any kind of infection or bugs. I've seen spots like that occasionally on a few of my plants. I think they may happen when leaves in full sunlight have small drops of water on them. The little drops act like lenses, focusing the sun and "burning" a tiny spot on the leaf. It doesn't happen all the time and I'm sure it has something to do with the angle of the sun and the angle of the leaves when the drops are present (i.e. before they dry).

Thanks so much LariAnn! You're wonderful! :) ....I feel better knowing they're not getting eaten up by something.
