I am currently fighting bud rot- mine started from heavy fog in the mornings and once it started raining it spreads rapidly- the initial culprit for me was catipillars- the little pest were eating my buds left and right- then the fungi attached itself to the injured plant material-I was taking mass amount of rotted bud away a couple of times a day- during a lull in the rain a I sprayed with serenade- it rained a couple of hours after that but the serenade helped- I also removed all, and I mean all the fan and shade leaves to help with air circulation- yesterday I found only 2 rotting buds versus gallons the day before- i resprayed with serenade yesterday due to the fact it has continued to rain - I could go on about my battle- I have read any and everything I could find on bud rot- serenade and air circulation are the only things that will stop it- GOOD LUCK my man you are going to need it with bud rot and rain
