What is the dense white spot on my plant? Please don't tell me it's powdery mildew. If it is powdery mildew, what do I do?

@stootie thank you. It's a good place to start my research.

What is your RH and do you have fans running in the room to circulate air?  

From the pics it looks like a little spot of PM To me.  If you have a scope PM will look like little webs up close.

My RH is between 50%-54%. I have 1 small oscillating fan on the tent. I have a 10X loop and have looked at it, but can't see it that well. I'll get a stronger loop and see what I can see.

Looks like PM...  Id carefully snip off any affected leaf parts and plan a spray ASAP .. even if you dont see any other visible colony like that, good chance more are taking hold. 

If you havent dealt with it before there are safe ways to spray in flower. Plan to up your air circulation ASAP also, its important for drying after spraying and will prevent more forming. 

I had it a few times as my grow is in an old basement.  I have to make sure i have air moving all the time, and doing a foliar spray ipm once a week in veg may also be helping, i havent had it for a year. 

Also, dont freak out...

As far as sprays,  I use Dr Zymes eliminator, Its a great product and is good to have around for the foliar spray and pests. Its totally safe throughout flower. People even use it as a bud wash step. Not sure if its available in your market.

Funny you say that. I just got a free trial package from them in the mail a few days ago. It makes a gallon of product. So I can give that a shot.

One other question. Do I spray and wipe? Or do I spray it and let it dry with better airflow?
