The new growths are softer and easier for bugs to eat. Now I think it is likely an insect problem.
I don't know what is available in Ecuador. An organic pesticide called Bacillus thuringensis or BT is the spores of that bacterium. They are spread on the plant. When insects eat the spores the bacterium kills the insect. This bacterium does not affect humans, and it is approved for use on organic food crops. The powder must be applied again if rain or watering washes it off the leaves.
When flowers die before they open, it is often because the plant does not get enough water, the temperature is too high, there is too much sun or the humidity is too low. I think your humidity is good so this is not the problem.

Yep, I second scale. From what I'm seeing the 2nd pics...those light brown scabby looking things look and awful lot like scale.
Scale usually leaves a round light colored area where they've been sucking so I'm not sure what the other areas are. Could be mechanical damage on those long-ish spots and/or scratched-looking areas. The scabs though...check those thoroughly and if it is scale...take care of it promptly because that is something that can spread quickly w/the warming spring time temps.
Negative for scale. I´ve had in the past and it´s not that, there are just that white holes.
it´s hot here but the temperature is constant all year so I think the orchids get used to it.
I dont have cats. The third photo im pretty sure is mechanical damage for my dog but the other ones are in a place that my dog cant reach.
I will look for that organic pesticide. but i´m sure I wont find it LOL.
I have some orchids with oedema so now I know it´s negative
Scale and oedema look much alike. Scale will rub off, oedema won't.
If it is not scale, then it is probitly oedema. Oedema looks like small brown blisters or can look like streaks of tan or creamy white. This is caused by the plant taking in more water than it can transpire. Has it been extra rainy or humid lately before you noticed this. This could explain the problem blooming (bud blast) also.
