What’s the white stuff, did you spray something? Or is that PM?

[Thickems]

Agreed, looks like fungal disease. Powdery mildew, leaf septoria. Mites would be only pest i suspect but not seeing any in pictures.

Did not spray anything.

agreed, looks like WPM on the underside and leaf septoria being the brown spots. id remove the affected leaves and drop your humidity to below 50%. Maybe even consider a fungicide or even introducing a UV light

Thanks. Ill do that. Is it ok to use a fungicide in flower? I ordered some captain jacks fungicide…

[jmystro]

Never spray anything on flowers.

[gulfcoastgrower]

Thanks. Understood.

A copper based fungicide can be added to roots. Let it dry back, monitor your watering amount. Agree with above to remove infected leaves, improve air flow, lower humidity and to never spray flower

Got it! Thanks
