Black, Purple, on my new growth and surrounding leaves What to do...

My outdoor plants had black yucky at the bud sites and surrounding leaves. I sprayed them with half Peroxide half water and it reversed the black purple dieing moldy crap. My plants are green again! I hope this helps anyone with this problem. I think the mold started from Catapillar poo on the bud sites.. so I brought out the Neem oil too! Hydrogen peroxide is my hero!

You can use that during flower or your in veg still?

Im big on DIY fixes/projects, thanks for postn the peroxide mix, will keep it in the plant hosiptal just incase
