powdery mildew?

[BlaZinROC]

I believe i have a powdery mildew problem on three of my endless sky plants 7 weeks into flower! what should i do? should i harvest early? At first i thought since the temps were getting down into the high 30's at night that it was just the resin glands reacting to the cold and almost freezing in a way but now after a week and further examination i see that it wipes right of in some spots. I'll upload pics of what it looks like later. Please, Help!

Get some Serenade and spray the plants. Serenade is safe to use up until the day of harvest, but it stinks to high heavens so you wouldn't really want to. Since you are a week or two from harvest, it'll be okay to use it now. Usually one application will kill the powdery mildew.

Not that it makes much difference now, but you should be running your lights at night, when the temps drop and you need the heat.

Get a heater in there and drop the %RH. If you've got the conditions for powdery mildew, bud rot isn't far behind.
As PC says, you need to schedule your on/off hours according to desired temps.

The RH is never higher than 40%, normally hangs around 35. Could it be caused from just stale air also? Also,i just got a small heater from homedepot yesterday that will kick on when the temps get to 55. Should i harvest early to prevent the spread?

Well, if you don't want to listen to how get rid of the powdery mildew, by all means, harvest them now. The bud won't be as good as if you went full term and, unless you've been flushing just for fun, the plants won't be flushed. But, it's your grow so do whatever the hell you want to do.:thumbsup:

55 is too low. Set the low-on point at 65.

hey PharmaCan, no need to be a smart ass. The plants only have at max 10 more days so harvesting 5 early is really no big deal. Also, they are organically grown and i've already flushed them once so there aren't really loaded up with chemicals so shortening that process is really no big deal either. Will the heat help drop the humidity because last night the low was 50 and the rh got all they way up to 70%. Also, How do i got about completely switching the lighting schedule, won't this stress the ladies flowering?
