Might be underwatered, but the important parts...are you using soil? What kind? Distilled water is not necessary or terribly healthy for soil plants...they would do better with mineral water....since you aren't feeding them anything yet they can get a bit of minerals out of the water itself...underwatering makes leaves droopy, or curl over...it sounds to me like it might be something to do with your medium, and you will never get good results with CFLs...some people post pics where they have done alright, but i started with CFLs because they were cheap and I could buy the bulbs anywhere...but by the time you spend enough monsy to buy enough CFLs to work and you spend the money on the power to run all of them you could have saved that money and just bought a 400w or 600w HID light...400w of power is 400w...whether it is spread between 20 cfls or one 400w light...and the 100w on the light is what it is equal to, but the plant's don't see light the way we do...so to them it is still only 23 watts you have there...so you would need 18 of those bulbs to equal one 400w MH...just because it is comparable to the light put out by a 100w bulb it is still only 23 to the plants...so right now you are trying to grow numerous plants with only 92 watts...which is maybe--maybe enough to keep one totally happy and growing the way it should...
So just something to think about...
