i wouldnt advice to spray anything anymore in week 6-7. My last grow i had some HP13´s in the room , and they were covered with mildew (they are very sensetive to that). But it didnt really effect the yield and bud. I guess that as long as its just on the leaves and not on the bud (which i have never seen) it aint so big problem although it looks nasty....i know.
yeah if it's late in the season when it starts, then it generally doesn't reach the buds. although i have seen it reach the small leaves on the buds and slowly even the buds.
hydrogen peroxide is one way to treat pm, but you can also use water with a high ph (8.0) by changing the ph you will kill the pm, lol. you can also use 1-2 tea spoons of baking soda per gallon of water and spray with that. the important thing is not to increase the problem with spraying. so you do it during light on, or just before light on. you unplug the lights and spray both sides of the leaves, then wait for 30 to 45 minutes for the air movement to dry the leaves a bit. then turn the lamps back on to help dry up the water. warm temps in the day phase and cold at night is also a cause of mold, as the water condenses in the buds when the temps go up and down too much.
in fact a mate of mine is only just 10 days in flower and he has discovered the beginnings of a pm infestation. i told him to use a bleach water solution to spray the walls and table and the baking soda solution for the plants, he will also add a heater more during lights off to help dry and warm the air.
