Query: Killed my Plants!

I've never used chemicals for my plants so I was very careful with this product. I like to keep my small garden 100% organic. I had problem with spider mites and my traditional methods didn't work well so I decide to buy something for organic gardening.This spray killed 3 of my plants!! Leaves turned black and dry after few hours I sprayed them!!!I don't know if it's my bad luck ... but I don't believe that this spray is safe. Not recommended!At least shipping was fast - that's why 2 stars ...
