Lemon Shining Silver Haze

I was looking other diaries and my plant looks very similar to the lastests grows, so i think it might be a genetical thing of the newest generation of this breed. Things never got worse, I'm actually thinking that my plant didn't get enough food because of my fear of burning it. About a week after this question I increased the amount of phosphorus and the stems became greener, I'm not sure if the two things are related.

Looks like grey mold for me and its bad.. Look closely under each bud, check her precisely. Hope its not but u have to check. Its weird while ur humidify is at 50%. But! It might false result while different parts of plant can have worse air circullation, so it does possible. If its that... u should remove each infected part and of course make a better windy climate Bless
