        And whats all those white spots, Bugs? Time for a look with a 30x (or more) zoom lens, look at the under side of the leaves also.
        What is "perfect PH"?

          I'm confused. Is this a Auto plant? It is flowering yet I see a three finger leaf. If so and the leaf is on the bottom of the plant, just pluck it. You might want to cut back a little on the nutrients.

            I'm also curious about the perfect PH

            Those spots look like spider mites to me.

              When my pH ran too high last grow I got similar patches on a few leaves on my sativas. It was a boron deficiency I assumed. They were a little darker though.
