New to Orchids - bought vanda seedlings without realizing difficulties.

You almost certainly don't have fusarium. Stop watching whatever channel suggested that to you. Fusarium does not manifest in Vandas with a red hue to the leaves. It manifests as roots suddenly shrinking down to threads even if humidity and watering are correct. People outside high-humidity climates don't need to worry about fusarium, especially in Vandas.

And stop pruning. Let leaves and roots alone until they turn brown and fall off on their own.

I only pruned the leaf that was already clipped and turned brown at the base and yellowed in the middle! I'm being careful. The leaf was definitely rotting and dying? My humidity a few days ago was 75-80% indoors and 78-80 Fahrenheit . It rained yesterday and the humidity went down to 57-60%
EDIT: i will also point out that that leaf was trapped under the left over dried leaf sheaf of a leaf that was removed by the nursary. I think water was trapped under that old sheaf that i finally removed to see brown on the leaf that I removed today.

The reddish tinge is definitely light sensitivity. I realized i was reading my light meter incorrectly as i dindt notice the x10 in the corner and my vandas were getting 16,000FC+. Waaaaaay more than they need. They were super close to the light.
