I haven't flushed.. I have it in a 5 gallon SIP system and haven't put in nutes since about 10 gallons of water ago. Can you tell me more about rot? Can it be prevented? What causes it? etc..
Bud rot is botrytis. It’s a fungus that will attack and destroy your buds. I‘m not sure if that one is bud rot or not but I get why he wonders. In general you prevent it by avoiding high humidity during flower. You want to keep the humidity at 50% or less in your grow room and get good air circulation. That means you want a hygrometer to test humidity, fans to keep air circulating and possibly a dehumidifier. If you look at any of the popular websites on growing weed there are lots of articles explaining what it is, how to prevent it, and what to do if you find it.
Three rules of life btw
1. don‘t eat the yellow snow
2. don‘t take the brown acid
3. DON’T SMOKE BUD WITH ROT
1 and 3 are mandatory 2 is discretionary
