Fungicide Anyone?

So I'm on my first grow and I have noticed a few spots of powdery mildew on my plant. I have taken off about half of a fan leaf on three different branches. I then sprayed with a mixture of milk h202 and water. I did this twice two days apart. About 5 days after spraying I have noticed another very small patch of powdery mildew on my plant. I removed the fan leaf all together and didn't spray again. 2 days after that I do not see any mildew, however I went ahead and sprayed with a natural and organic fungicide to be sure it does not come back. The fungicide I am using is dr. Earth final stop. I am curious to know that since my plant is now budding, is it safe to continue using this fungicide throughout flowering. It is humid here right now and I fear for problems with mildew and even more for budrot. The bottle says that it is safe to use up to the day of harvest...but then again, you don't smoke tomatoes. As you can see from the photos, the ingredients are listed, however I don't have an incredible knowledge as to if anything in there is "dangerous". Any replies would awesome. I'm about 3 weeks into flower now btw.

Ok so I'm on my phone and it won't let me upload my photos:-/ so I am going to just name ingredients I guess.

Rosemary
Clove
Peppermint
Malic acid

Other ingredients

Bentonite
Carrageenan
Cellulose
Citrix acid
Citrus pulp
Dolomite
Glycerin
Guar gum
Kaolin
L absorbing acid
Sodium bicarbonate
Soybean oil
Water
Yeast.

That is the full list.

Thanks again
