I am so glad you posted this thread!

I have been having the same type of white spots appearing in my plants leaves for a couple weeks now. I sprayed my plants with a little, diluted soapy water and rinsed the infected leaves, but nothing changed.

I checked the plants with a magnifying glass closely on both sides of the leaves, but never saw any bugs crawling around, so I just guessed that it was a pH problem. Maybe some type of nute lock-out like Jdog7000 said.

I will post a picture tomorrow as I will have my camera back then. Let's compare! :smokin:
