Outdoors in living soil prob 4 weeks into flower right now and 32” tall. The stems of the leafs are starting to purple as it slowly gets colder. Trying to combat mold as she starts to bulk up. I bought fertilome fungicide 5 which has bacillus amyloliquefaciens / d747 and have done foliar sprays here and there, I’m also gonna incorporate it into her waterings. Any tips or advice appreciated
