How far along in flower are you?
Honestly If you have established buds, there isn’t much you can spray in flower safely.
if you try anything, remember to do some reading and see how it will effect the buds. Don’t want to make your crop a “bad smokeâ€!
Edit: I’d consider a PM wash with h2o2 water if your just about done. Don’t want those spores active during curing stages
