If it’s spider mites you’ll need more than just Neem oil for the win.
The damage is done but if you stop the infestation from getting larger by a multi pronged attack of different treatments it won’t get worse and she will recover.
Castile soap and water (not detergents like dawn)
Diatomaceous earth
Many things to use especially while in veg.
In flower some things you don’t want to use like Neem oil.
