| I grow hundreds of Vanda outside here in Florida. My first opinion when I saw the first picture was excessive heat in the summer.
Your later post confirmed it when you said it started last summer. I have a test Vanda growing in full sun year round (11,000 foot candles and temperatures to 100). It looks like your plant or worst, but Oh dies it flower well and often. The high light turns the leaves yellow since the plant does not need much chlorophyll it reduces the amount in the leaf.
More shade may make the leaves look better, but may reduce flowering. It is your call.
