Plants look sad, watering issue?

This is my first medical hydro attempt and I am determined...
They were bare root clones i transplanted (almost 5 days ago) into pre-soaked plugs and put them in 6" grodan cubes. As instructed by my local hydroponic dealer, I soaked and rinsed the 6" cubes with 5.5, put them in pots on a bed of rinsed clay pellets about 1 1/2" high. Pots are in a 3x6' flood table under 1000W MH about 4' away. I added a small amount of nutrients, PPM about 800 and flooding table twice a day for 30min each. water level doesent seem to get above clay pellets, or maybe just a little... Is this right?
I can't figure out why they still look so sad... watering issue?
oh and room temp stays between 72 and 76 but cant get humidity above 40%...
Any help would be appreciated!

Lol. Alright i dont know if this is your first grow or not. Considering the info probably not. Anyways, nice light good pot size might need to transplant after awhile but my guess? No flooding. The water should not be getting above the clay pellets but hitting your roots. Too much water and your drowning your plants. Also try putting your light just a little closer and are you following the 18/6 regimen? You should.

Haha, this is my first Hydro grow... I have my light on 24/0 I heard this helps veg more vigourous..? also, I heard that drooping leaves was a sign of underwatering, but I know overwatering has the same affect, should I stop flooding for a day to let the medium drain out some of the water or should I just cut back to 1 - 15min flood a day?
Im going to drop the light today, should I lower a few inches a day or should I drop a couple feet now and then I few inches a day until it is closer?
Haha I know Im all over the place... I appreciate any feedback
