Does my phalaenopsis have thrips?

[akhenenra]

Any thoughts on this would be appreciated, I will try to be brief. My setup with my orchids is they are grown in a tent in my basement, and when they bloom I take them up into my house to enjoy them. In the tent it’s 68-80 degrees F, around 80% humidity. Upstairs it’s more like 72, 40-60% humidity, normal house environment. They do have a grow light upstairs but not nearly as strong as the tent light. This phalaenopsis finished a spectacular bloom about 6 weeks ago, I had 24 flowers for almost 3 months. Since then it has developed this discoloration and roughness on the older leaves even as it pushes out new ones. I sometimes get a little bit of environment shock bringing them upstairs, in the form of bud blast, but I haven’t had issues returning them to the tent before. I try not to be too panicky with my plants so when I first saw the yellowing I wasn’t too concerned, but it has gotten progressively worse. Any thoughts are very appreciated. The small white/dry spots are older mechanical damage, there are also some small mineral spots on the leaves- it’s the color and texture that has me more worried. I have sunburned one or two of my higher light plants in the tent before, but never a phalaenopsis, they are pretty far from the bulb.

I made this exact post on a different orchid forum which will remain anonymous, and someone said outright that it's thrips, I must throw away this plant immediately, and I should expect them to slowly take out my whole collection. So....I'm looking for a second opinion on this, obviously I'm hoping it's not quite as dire as that. I've had thrips on other houseplants but never an orchid, I honestly didn't even think of it until the post. Appreciate anyone’s help! Cheers
