What's this on my tomato leaves?
Its more brownish than the white color that shows on my screen. The plants have been under lights indoors, swapped outside on milder days; had one foliar spray of very dilute Miracle-Gro and been rained on a few times since.

Hey I recognized the damage as something I’d seen before and felt that it’s not serious and seedlings will grow out of it, but couldn’t remember if I’d ever found out what was the cause.
This seems like the right one — what do you think?

The damages are observed as sunken, tan to brown leaf spots.

This damage is consistent with cold damage. In a hard freeze, the entire tomato plant will collapse. However, when it is actively growing and temperature are unusually cold, these symptoms are typically observed.
