thanks again, Louis. I am with you, I use up what I have started am wondering though if I should increase the dosage maybe by 1/2.

Tanya, in liquid form you use 1 Tbsp/gallon after you shake the bottle up thorougly. It is thick stuff so I guess you could make a thin slurry and use half the amount usually recommended. If you don't see a white film on the leaves after, just increase the powder to water ratio.
