help , one plant drooping looks dead

[ectomorph2013]

i have 3 serious seeds chronic in an nft system ,, plants are 2 - 3 foot high and healthy last night. just looking in cupboard and one of the plants (the biggest one) is all droopy and nearly dead looking .. filled the res 3 days ago ,, 500ppm nutes. plants in 3rd week of veg. this is the plant with the most roots. when i looked at the rockwool cube it is in ,, it had what looked like a couple of dark blotches when i rubbed my finger on it , it came off like powdery soot , black. I dont know if this is related...

I dont think it is nute related as the other 2 plants very healthy looking , so far :/


please help

it looks like to much heat or water starved ,, the heat is a little high at 85 during the day, but iv had this strain grow hotter than that. the nft system is working fine. the other 2 plants are strong and healthy.. Im hoping this isnt something that is going to spread

hard to see with the light on ,, its the plant on the right

Oh yeah she isn't looking to good, can you look at the roots at all to make sure there not rotting or molding?

 

[ectomorph2013]

the roots look the ok ,, just off white colour

im scared this spreads to the other 2 ,, that girl was the same size as the one on the left last night

Plants are touchy a day u should see a difference

thanks for your help bro , fingers crossed. the other two dont seem to be affected so far

 

[ectomorph2013]

im hoping the black soot like dust patches on the rockwool i mentioned earlier are not some kind of disease / mold that will spread to the other 2plants :/
