Spots on leaves

Is this powdery mildew? If so How can I get rid of it???
Newbie to this stuff
We did dip our plants in a mixture of rose defense about 2 weeks ago for spider mites. This is just showing up.. Our room is well ventilated and has a humidty of 44%
Please help with any and all advise.
Thanks in advance.

never seen anything like that

Has no one seen this. Is it not Powdry mildew?
some one please HELP

I have not seen it before, but I would suggest keeping the leaves attached to the plant, seeing as how they're still almost completely green. Unless it's contagious or spreads to all the leaves, I wouldn't worry too much.

that looks like mold to me.....does it rub off with your finger....and were these the bottom leaves...or is it at the top of the plant

yes it rubs off easily with your finger. It is at the bottom and close to the top? I am pretty sure it is mildew. but How do I get rid of it. We are in the 4th week of bloom with alot of buds.
Thanks for the reply

check the grow faq. ........ive also heard neem oil is a good way to get rid of it...

Noooo neem that far into flowering.
