Omg did I burn with my green cure?!?!?

in an attempt to help my babies fight powdery mildew I gave em a hefty foiler with a heavy dose of green cure I flushed a plant today but sprayed it on another and instantly noticed burns is this the case I never got burns with actual
Foilar feeds but can this happen with fungicide???!?

If you sprayed it on and "instantly noticed burns" as you say you did, then I would suspect that it can happen

Think I should cut back the colas or let em heal?

Let them heal. It is a bad case of Phytotoxisity.
