Light brown textured spots on Cattleya

[SakuraDrops]

Hello all,
What do these marks mean on my cattleya?

Photos: Blc Hawaiian Island Bride 01 - Album on Imgur

Type: Blc Hawaiian Island Bride "01"
Location: Houston, TX

Current Care:
- Potted in medium sized bark

- Water 1 - 2 weekly, I give the pot a good soak when it feels light.

- Fertilize every 2 weeks

- They are outside in the morning (very humid, 7-8am until 12pm)

- Once I bring them in the house, they are by the bright filtered window as you can see in the photos.

- 50-60% Humidity indoors

- I keep their room warm and muggy. 78-79F

I want to share that, two weekends ago I left them outside longer than intended, they were in direct sun for at least 1 hour. There was a mark on only ONE leaf, but since then it seems that other leaves are getting these marks as well. They have not gotten ANY direct sun since that weekend.

Please share any opinions or any other care tips you may have, it is greatly appreciated as I am a beginner. Thank you! <33

Looks to me like sunburn. It doesn't take long for damage to happen.(Minutes) And slow development of more signs of it is also normal. The plant will be fine, though you'll have some ugly spots. Those will be a reminder to not do it again... Don't be tempted to cut or treat. The damaged leaves are still photosynthesizing and supporting the plant, Eventually, when the plant no longer needs them, the damaged leaves will drop, but by that time, in a couple of years, you'll have new growth.

You are working much too hard with the indoors-outdoors routine. Find a good spot (likely indoors, near that window) and just let it grow. Temperature is fine, Catts will also tolerate quite a bit cooler, they're quite forgiving.
