so do you think you had those spores (or however the mold begins) already in your room and they were dormant? Or they were brought in from somewhere's else?
Well those spores are literally everywhere. So i'd imagine they were in the room and the conditions made it so it grew.
They say with bud rot(botrytis) that an ounce of prevention is worth a pound of cure. I know mine was caused by environment and bud structure. Small airy buds are affected less than big dense buds as there is less airflow to the center of the buds which is where botrytis grows from. Often you don't know you have it until you see a brown wrinkled leaf. I saw that a Monday and was like ehhh this doesn't look good so I opened the buds apart to look inside and saw a lot of white. This plant is very trichome filled, but I saw that the bud kind of broke apart a little and was brown inside which is another less apparent sign that you dont notice until you spread apart a bud. Plus mold structure is way different than trichome structure. Noticably lacking a head.
I've only had this one other time over the summer. But they say most indoor growers and all outdoor growers will have an experience with this given enough time growing. Once I get a handle on environment I don't ever expect this to be an issue again.
Going to do a 50/50 mix of water and bleach and clean the walls even though I don't think any active spores made it airborne as none of the other buds are affected and by the looks of it I caught it early. I've seen pictures of peoples plants much worse off. But there is a chance since I opened the bud in the room. Normally you'd want to cut the bud out and THEN inspect. But having minimal experience with botrytis and since the plants leaves were discoloring because of deficiencies I didn't want to chop an oz cola off on what could have been a deficient leaf.
