Alright so I have a Blue Mystic in flower and she has had a few of these strange leafs for a few weeks now. Originally thought it was because our ph was too low at 5.9 and was causing a cal/mag issue but we use cal/mag and got the ph back up to around 6.2 I took a clone a few weeks ago and rooted her and now I have this developing in her as well. Anyone know what might be causing this? Genetics? Nute sensitive? Thanks. View attachment 117958 What type of medium; soil or hydro? SOIL What brand and type of soil? FFOF Indoors or outdoors?
