It's pretty hard to diagnose the problem without a picture, but from the questionnaire you filled out I did notice one thing

your ppm should never rise on daily checks, this is an indicator that the plants are absorbing less water than nutrients, which can lead to burns, and toxicities, however your pH is rising at the same time too, which is not supposed to happen

Although i don't know why your leaves are drooping, I do know that if the ppm rises on daily checks, as a side effect the pH should fall.

I would guess that maybe your problem is related?

Pictures would be helpful!

Sorry for the late pictures, I was at work. They are indeed drooping and starting to burn. I have turned off the drip system to see if this would help (The bubbles are still going though).

Please help, I don't want to lose my babies!!

They look over watered and over fed to me.

I'd dilute the res to 500 PPM or so.

I've diluted the res and they continue to get worse.

I took a look in the tanks and there is some foaming and lots of slimy bildup on the ouside of the tubing, and I'm wondering if this could be the cause.

Before I waste an asload of time trying to clean em out, are these plants even going to be able to be saved with all the shock they have suffered, or are they a lost cause now?

What size air pump and what air stones do you have in there? Temp of your res? What do your roots look like? Sounds like there is some rot going on.

the roots don't look too horrible, though they seem to be clumping together in some spots (Since they all grew out the same spot in the netpot).

I have a single 20gal air pump pushing through to a 6" air stone in each bucket.

The drips are on small 10gal water pumps set to water 10 minutes out of every hour (Was previously running full time).

I'm really not sure what I should be doing to try and get them looking good again?

Should I drain and completly wipe out the tanks? Should I just leave it for another few days and see how they do?

I was planning on draining them anyway again this week so I could start flowering, but with them looking so sickly, I'm not sure I should do anything.

Not only are they dropping, the leafs are not sprouting like they were before I changed over the res the first time.

*sniffle* I don't want my babies to die!!!!

From the top, they don't look bad at all, maybe a bit "over watered" which with DWC means not enough dissolved oxygen! or maybe the bottoms of your rockwool are too wet

without seeing a picture of the roots, the foam/slime you described could be the start of a problem. Are you using any preventative measures agaisnt pythium? (hydroguard, aquashield, hygrozyme, etc..?)

What's your res temps?
What kind of air pumps/discs do you have, how many per res?
Do the roots look discolored?
Any smell?

It wouldn't be wasting time cleaning out the res, I've seen plants 10x worse recover! (yours don't even look bad at all!)

If the roots have reached the res there is no reason to have them on a drip any more..and splitting that little pump up 6 times could be a bit much for it, and there is not enough o2 floating around.
