Great product, one of my favorites. It works better for prevention than treatment, but ymmv. I would get this and potassium bicarbonate both. Just get the smallest bottle of the Southern Ag, it makes more than you will probably use in 6 months, which is how long they say it stays fresh once opened. I'd treat with potassium bicarb then follow it up a few days later with the GFF. You'll probably need repeated applications to make an impact, good luck!
