Do you mix your nutrients on a per plant basis, or do your plants share a batch of nutrient solution? I'm wondering if you got too much of one, and not enough of another nutrient in one of your solutions. It's possible when making small batches of solution that the scoop of MC used was not as homogeneous as we'd like. If this happened flushing should take care of it.
At this point we're taking a stab at what might have caused it. I'd take a close look at the roots when you harvest or destroy the plant. It may or may not give us a better idea of what's going on. Right now I think most of us are scratching our heads and saying 'HUH?'.
