How much Exel LG to use for powdery mildew?

Hi guys--I need help ASAP! My plants all have powdery mildew from bringing in a diseased clone.

I purchased some Exel LG, but I have no idea how much of it to put into my 40 gal reservoirs. Anyone know? The directions are convoluted, and I'm too uneasy to just guess and hope for the best.

Also, anyone tried it in a foliar spray? How much do you recommend using per gallon?

Thanks!

I read 1-2 tsp/gal on the booklet it comes with

if you're looking to use it as a foliar spray, i believe it's 1-2 tsp/gal. so if you looking to mix it inside a quart sized spray bottle, it would be between 1/4 tsp - 1/2 tsp/qt. however, if you're looking to use it as a drench for your reservoir or for soil drenching, it says to use 1/8 tsp/gal.

i just got some if this stuff and had been using safergro's mildew cure (which really doesn't work too well imho) so i'm going to use the exel lg as a drench for my coco and will also spary in conjunction w/mildew cure.

now if this don't work then....? ahhhhhhhh!!!!!!!!!!!!!!!!!!!!!
