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.
