Help with phalaenopsis lighting adjustment

[Foogoo]

Hi all, I have a collection of phals on my bay window (east facing, Southern California) and they started burning over summer, so I immediately moved some out and shaded the window with paper. Now, I'm confused as to whether they're still getting too much light or not enough.

Some of the larger leaves are turning light greenish yellow (too much light?) but most new leaves are long and thin (too little light?). Most of them also have a reddish tint (too much light?) and are a dark green (too little light?)

They seem to be giving signs of both too much and too little light. Since I'm in a condo complex, they get shaded direct light for about 2-3 hours in the morning. What do you think?
