you have the weed herpes bro Powerdy Mildew... these are all bandaids at best you need a systemic herbicide like Eagle 20 EW

I used a mixture of Einstein oil (neem oil) and greencure in the same 32 oz spray bottle of water... held it off for about 10 days.

1 spore is all it takes and you got a problem...make sure you clean your walls floors ceilings ..everything in your grow area with a 1/4 cup bleach to 1 gallon water mix

They do have fungus bombs now too FUNGAFLOR TR....just like the bombs for mites...use the fungus bomb on your grow room....it will be like using a sulfur vaporizer without the smell

I would spray your plants top to bottom... you want 100% coverage on your plants.

I havent tried the bomb on plants yet.....so I wont recomend it for use on plants ..yet:hippy:
