Plant got droopy overnight! Help!

Can anyone tell me what to do? Ph is right, temp is right, nuts are fine......HELP!

Check out your roots, are they slimy, brown or smelly? That looks like the start of pythium.

I'm on my way back to check.....what do I do if they are? How do I correct this or am I SOL?

looks under watered to me, sometimes when I would forget to water my clones for a few days they would completely sag over like that, but as soon as I gave them water they would stiffen right back up and be fine

Nah....they're hydro bro....always in water.....
