We use different water, I do not have spider mites, it is not a mold to microscopic exam.

So, I only see in during the last 3 weeks of flower. I am trying Cal/Mag now, but I noticed it really dropped the ph of the water and I had to buffer it first. Next time I give less than the advised I think.
Tx for the input! I just wanted to add that the leaves get brittle as this stippling progresses. Still trying to pin this problem down . . . not 100% sure of the cause yet.

I keep looking through the diagnostic pictures in my books (which are pretty extensive), and I'm not seeing a leaf that has this weird stippling. Virus? Aliens?
