Massive damping off

In my 8 years of starting tomatoes, I've never had the amount of damping off as I've had this year.

The seedlings, suffering from too much water, nitrogen, and/or shade, just flop over and there is necrosis at the soil line.

I definitely noticed it with seeds from one supplier. My own stock of Snow White Cherry have not suffered in the least. It seems quite random.

Fingers crossed the tomato pogrom has stopped.

Still, I reckon there will be over 200 healthy ones to give away. Yay!
