Help!!! Little reddish brown spots all over my phalaenopsis leaves

[Chelsea kahana]

So I attached 3 of my phalaenopsis on my palm tree in my yard about 3 months ago. One of them the leaves turned really yellow from to much sun light. But when I took a closer look there are do many reddish brown spots all over the leaves. Its also about to flower doon since it sent out 2 flower spikes a while ago. But the plant does not look like its healthy anymore can someone help
