Welcome to the Orchid Board!

That is a Phalaenopsis orchid. It looks mostly good. There might be several causes. The brown spots look like old mechanical damage, like from scraping or crushing. The leaf might be yellowing because it is getting old and dying naturally. The far edge of the leaf has some silvery blotches which I can't see well. That might be mineral deposits from the water, or it might be spider mite damage.

What are your growing conditions? Temperatures day/night? Relative humidity? What kind of light is it getting? How often are you watering, and how do you water? Do you use fertilizer? If so, what are the numbers on the label, and how do you mix it?

Answer: Yes i suspect mineral deposits i attached the photo.
What are your growing conditions? I actually repotted the entire Orchid in the pot with mixture of Charcoal and Coco husk
Temperatures day/night? relative stable around 26 to 32 degree celcius
Relative humidity?very humid since i live in Indonesia What kind of light is it getting?Indirect light from the window, as i put it inside the bathroom
How often are you watering, and how do you water?
I just water 5 days per week and i will soak it inside pot not touching the leaves just the roots and let the water drain from the pot
Do you use fertilizer? If so, what are the numbers on the label, and how do you mix it? i bought it from online they only mention these ingredients, i usually fertilize it after i water it.

I think it's just an old leaf dying normally. If your humidity is high you probably don't need to water 5 times per week. Once to three times per week would probably be fine.

Thanks for the advice, how about fertilizing?

How often to fertilize depends on the nutrients in the fertilizer. A small amount once a week is usually enough.
