Phals: Brown spots and more - pictures

[Ross]

I used to grow mine outside, but after the hail storm that descimated my collection....

It certainly looks like pretty full sun to me. The purple coloration is fine. It just means you're pushing it with the light. I like to see that on mine. The brown spots usually signal a sun issue when the plant is wilted (dry) or sick or just plain too much UV. I've done that before myself. It will never correct the bad spots. The last photo is something else, I think. I'm suspecting you spritz your orchid with water while the sun shines. Never do this.
