Yes, I had read that article, so I thought it could be edema, I have seen blisters even in the flowers but what caught my attention was the irregularity of the edges of the pseudobulbs. I also think that the excess of light with consecutive days of water, have to do with this. I applied daconil when I saw them, I didn't notice any changes, now I plan to apply some insecticide to the thrips. I will not worry more about these spots although I will watch them closely. Thank you very much for your help. Regards.
