organic dwc+drip using compost tea

Ok.. Little update. The system is up and running. 40gal res with powerful biofilter+pump (DWC).
I have questions tho.. Currently I have two plants on my system. Both from same mother and they are both taken at the same time.
Both are same size. But.. (then comes the but..) Another plant has beatiful white roots with lots of hairs on them and another has brownish roots (not looking as vibrant as others roots). What may cause this behaviour ? Both are on the same DWC res. Im feeding very very little nutrients and compost tea. The brownish roots do not have any slime on them. Im little bit conserned what is happening there. Any suggestions what may cause this ?

Just to complicate more this things
Furthermore, growth depression (Table 1) and browning in roots occurred several weeks after the high root temperature treatment. These effects of high root temperature was considered to closely relate to the reduced oxygen solubility and the increased enzymatic oxidization of phenolic compounds that produces brown substance in root epidermal and cortex tissues and causes depression in activity of root physiological functions (HURD 1978, FUKUOKA & ENOMOTO 2001, WEELS & EISSENSTAT 2003).

This study deals with effects of high temperature stress and salt stress on root physiological functions
.root pathogens---many of them tend to scavenge N, they also coils around non suberized fresh meristem blocking the uptake of Ca... afterwards all is collapsing...or counterattacked by plants inmune system.
.2 clones from same mom---if they are both healthy then yes, they are two copies of a healthy mom
.uptake of Oxygen--pathogens will mess up with the current roots cell spezialization/distribution. Also the sensibility to the lack of oxygen due to heat shouldnt be discarded.
.slimes are usually polysacharides and glyco-things but not all microflora produce them
hope it helps in some way! & welcome to the maze^
