Troubleshooting

CBD Plants outoors. Strain is Cherry Wine. What is the best way to deal with it and does anyone have any formulas they recommend to control it. I understand copper based or being said based formulas seem to be the best treatment. Thanks for any help or formulas to mix to treat the fungus.

Looks more like potassium and nitrogen deficiency to me.
It’s just a couple leaves here and there, outside grows you lose a few leaves here and there.
