These plants were in 3" pots, started 3/29. I water 1-2 times per week and have a fan on them. Last week I watered with a diluted fish emulsion for the first time. The other plants did not have this reaction, but I do think this bunch might have gotten a stronger dose? I bottom water and the yellowing is from the bottom up.

I was concerned they were crowded in the pots and near each other, so I potted up on Monday afternoon into 20 oz solo cups with drainage holes. I dampened the new mix when I potted up but did not water. Slight improvement on all plants but one, which I lost.

The San Marzano, pictured is the most yellow. Any ideas? Is this disease? Seed borne? Could I be spreading it via the fan?

Should I cut the water to 1 x per week? Should I not fertilize again?

I'm hoping these plants can be saved.

Why is it still not planted out given your zone?

PS: Watering isn't a scheduled thing. It is as the plant needs it. Some may need it 2x a week, some 1x a week, some 1x in 10 days. You know if the plant needs it by sticking your finger deep into the soil. If it is cool or damp then it doesn't need water.

There is no moisture a finger length down in these new pots today. Good to go now? My fingers aren't exceptionally long, and there is still half a pot of space left. Kind of gun shy about watering now.

I didn't plant out yet because here in the Bay Are we have our hottest months in the fall, particularly September and October. I start seeds around the first of April and plant out mid to late May to try to catch that heat. These plants came up exceptionally fast this year. I'm trying to hold them one more week before hardening off and planting out the weekend of the 17th.
