I don't think it's from too much light. The round spots look like insect damage, the others look like mechanical damage like the leaf was folded or bent and cracked. It could have happened a while ago and scar tissue developed later.

The leaves do look a little dehydrated, could be from not enough water or from roots getting too much water and rotting. Could also be low humidity high heat. Or quit a few thing. It all depends on what your environment is like.

Where do you live? What zone and how are you growing this plant. Hard to help without further info.

nothing to be concerned about, your plant is fine, the ribs in the leaves are a good indication of good root system, I would not change course on whatever you're doing to the plant

My zone is 9b - 10a. The phalaenopsis receives some hours of, basically, full sun everyday, thanks to my window's lack of curtains. I water it every 4th day (but sometimes i kinda forget the day i last watered it, so it might be more like every 5th to 6th day). I bought the orchid 4 months ago and i am waiting for its 'dormant' period to repot it (So i haven't fertilized it yet).

The orchid has received some mechanical damage indeed. My empty-headed roommates threw it on the floor more than once a couple of weeks ago. The average relative humidity is around 55% (First half of the year) and the average temperature is around 64F, but it varies greatly through the day. Some solenopsis sp. are the only insect i have ever seen around my orchid.

Thanks, i get kinda nervous every time i get a new family of plants, so every little problem must be solved. I am more of a Cactaceae kind of guy, so orchids are quite new to me.
