I noticed the root browning yesterday and started using H202 to keep clean roots! I will keep close eye on themDecent growth, but they look a bit brown to me. Do you run Hydroguard or similar to maintain your good bacteria? If the plants are otherwise healthy, pay no attention to me.
Look into hydroguard. It's the shit for healthy roots. It is a mix of good bacteria that keep the bad ones at bay. Also, keep a close eye on your airstone; roots tend to go bad when the water isn't oxygenated enough. Bad airstones will cause root rot.Big bud #2
