What is happening?
 

My plants have been doing extremely well, and still are but I keep picking off these types of leaves with dark spots on them :( They are grown indoors. I have only seen 2 teeny tiny beetles on them (which have been removed and are dead) so I don't think it's them.

I think my plants were retaining more water and thus why this occurred. I'm on it! :D

So you think you have a mild case of Edema? Any blisters on the lower surface of the leaves?

Hmm..not that I've notice.... I did spray them after I posted this with Baking soda and water...I cut off all the leaves with the spots too. So far so good...I guess we'll see :D

Edema is not a disease, it's a physiological condition where water transpiration from the leaves is slower than water uptake from the roots causing cells to burst.

Thanks for the info :)
