Phal Leaves - reddish edges and floppy

[LadySoren]

Another sad orchid needs help::

I am posting pictures of my Phal. It's a ""White/ red lip Dtps. Ching Ann Angel"

It is currently under a 23w 6500k CFL bulb in brooder clamp light about 12" above leaves.
Before that its light source was just a small nightside lamp stand with no shade, bulb sticking straight up. Changed to the clamp lamp because I asked here on the board what I should do for easy cheap lighting (bad window situations where I live) and that was a suggestion.

A few months ago, one of its 3 leaves got really droopy. I thought it was no big deal because it was the oldest leaf. Now 2 of 3 leaves are floppy and all 3 have a reddish tinge around the edges. Some of the roots also have a red-brown appearance.

I have googled and googled, and some say it's too much light, so say not enough, some say too much fertilizer.
I was fertilizing it biweekly and, in my noobie opinion, it was "weakly."

As far as the floppy leaves go, I read that maybe it was not enough moisture. I water weekly, but it's in bark and good drainage. For a few weeks now, I have added bowls of water to sit around my phals (haven't gotten to humidity trays yet). I know once a leaf has flopped on an orchid, it will stay floppy because the damage is already done.

Will post photos of various stages of its life so far with me (since February this year '13) for comparison.
By the way, it had 5 leaves to start with. I repotted from moss to bark and when a little insecticide crazy in the beginning. Oops. But the leaves didn't start getting red edges until the last month or so. Was in sad shape before the clamp light, but not this bad at all.

Anyway, see photos and please tell me what you think.
The mini phal I have right next to it under the light is flourishing. A bit of brown roots (I really think it's fertilizer burn), but it's on it's way to SIX really happy leaves and some more bright green roots.

Let me know what other info you might want to help me diagnose the problem.

THANKS!
