It looks like mold! I discarded all the moldy parts (only 3 spots in the 2 plants) How did this happen, what caused it to mold? Humidity is only 61%, these were the only plants affected! Could it be where it was lying up against the mylar on the wall? I have flowered 3 times, and this is the first time I have ever seen mold! What do you guys think? How can I prevent this next time?
