(Updated) Weird black spots and yellow leaves on my den

[Synrosion]

I got this Den awhile back the specifics are in the photos below. I water it weekly, and I live in Florida so it’s in non direct sunlight. I need tips on what to do with it for the conditions to be better. But the leaves look weird for an orchid who’s just stressed.

Make sure you don't have spider mites.

Dendrobium tobaense doesn't like hot weather.

This group (nigrohirsute) shouldn't dry out. Depending on what it's potted in, and growing conditions, once a week might not be enough water.

It’s potted in orchida bark. Does it look like mites to you? The leaves look like that and the blooms stopped opening

Would spider mites explain the discoloration on the leaves? That’s what’s worrying they turn into that than fall off. I moved the plant indoors again like it was since today
