Hygrozyme and sensizym will help but it depends on how far along the root rot is. You can also try h202 at 3-5 ml per gallon(watch out,this will kill any organics you have in rez). What are your water temps. you want them to be around 65-68 F. Anything above 70 and your asking for trouble.
BlazeIdo Reviewed by BlazeIdo on . PLEEESE HELP FAST my roots look funny in my nft424. they are discoulered brown and i have had to empty the bottom tank twice in nine days. because there was floating and sinking gooey browny clulored stuff wat kept blocking the water pump as well. i have used nitrozym for the first time and read that this does discolour you roots. but my m8 has the same batch and his roots are big and white and look good. my roots look stunted to about a foot from one side to the other and look brown. my plants still look good Rating: 5
