I think two of my plants got nutrient burn. Either that or the PH was fluctuating too much. Anyways, the bottom set of leaves seems pretty dead...should I cut them off or leave them alone?

They look underfed and over-watered.

overwatered? It's a DWC system. The pots are about 2 inches from the roots. Please advise.

That doesn't make sense to me. I added a bit more nutrient to the water and today the leaves are curled like mad. Please help me.

The PH is around 6, the temperature is kind of high at 82.

That looks like a magnesium deficiency (because the veins are still green), what nutrients r u using on them?
here is a sick plant guide that will help you out http://www.icmag.com/ic/showthread.php?t=11688

Looking at the pictures it looks like you have some salts buildup on the rockwool. you might even have nute lockout

I read the sick plant guide about the magnesium deficiencies. I added some Fulmag to supplement. How long should it take before I notice an improvement? I've got almost 800 dollars in this grow and this is pretty depressing. You mentioned nutrient lockout. What would be the cause of that? Any advice is greatly appreciated.

Looks like your plants are curling downwards? Mine are curling up like a crippled hand. I've about decided to transplant them into a soil system. I've already moved three plants...i'm gonna see how well they recover before moving all of them. Good luck.
