I checked for bugs and don’t see any.
The leaves are not wilting and other than the dots, the plants look happy.
We sterilized the soil mix in cooking bags in the oven before starting the seeds.
All plants are still inside our beach house/sun room...
Compare it to pics of ‘early blight’. I take care of that with a spray of a bleach solution.
5oz of the clorox concentrate bleach + 1gal exactly of water. Mix thoroughly and spray till saturated AFTER the sun goes down. Sun + this solution == burned plants.
If other plants are present in the sun room , all the more likely that aphids may have overwintered elsewhere.
Check the bottom of the leaves with a magnifying glass for possible beginning of aphids, or white fly .
Well if you sterilized it then if you got it above 160F it’s probably not wilt, unless you smoke and don’t wash your hands before handling the plants, which is a vector. If it’s harmless so far to the plants, then I guess nothing more you can do but keep an eye on it.
On that note, was going thru the Gardens Alive! catalog today, they got a number of treatments for virus and fungus problems based on friendly organisms you can culture into the soil. I may try them to get rid of my own wilt issues this summer.
