Doc in the house? Sad plants, ugly roots

Hey,

I AM IN DAY 10 OFflowering
\i go into room this morning and there are 6 plantsside by side all sad.

I have examined them and the only noticeable difference is that the roots on the bottom of the rockwool cube are brown.
Whats causing this?
How can I fix it?
are these plants ruined?

RH- 60% when awake 80% when sleeping
Temp- 78D when awake 72D when sleeping
5.5-5.6ph
1000 ppm

Pictures will get you replies

not @ home right now,\
I can draw a picture of a sad plant(looks like its sleeping during the lighting period)
and roots at bottom of rockwool cube, where they are normally white, they are now brown

I have been researching,
I may have overwatered them

try research root rot

Yeah sounds like a fungus. And when u said RH% that means ur room humidity correct? if ur room humidity is 80% when ur lights r off that sounds way too high. That could be causing the fungus growing on ur rockwool, peroxide might help unless its become infected all the way thru the wool. Look for a dehumidifier.

give it some h2o2 and see if she will recover mate, root rot or over watering.

what are res temps?
