Pics will really help... a lot.

Some add's leave a film on roots. Some mold/bacteria can grow on them too... both good & bad. Black/grey "sounds" bad though. Pics brother! Peace.

what kind of system you running? IE (flood and drain, dwc, aeroponics)

get you some hydrogen peroxide, just put 1/2 teaspoon per gallon

Do you change your rez. regularly? It sound like mold and if you had a moldy airstone then that is probably what it is. Lollipop is right with the HP though.

for future reference you should monitor your nutrient solutions temperature to avoid root rot. It's caused by the root zone getting too warm, and not changing your reservoir solution enough.

 

[lollipopman]

how does the roots look?

 

[mickmick]

i change the solution every 7 days. thanks for the info.

 

[mickmick]
