Yeah, when I saw it i got a bit of panic, but now I'm calm again. She were standing where I have the cold air coming in, the affected bud was on a lower branch wich didn't have any air-movement. Yeah, we have got around 18-20 with clouds and rain everyday. I will have 2 eyes open and try get more air circulation.
Thank you.
And I'm really impressed of your grow, you do this every summer?
