What's wrong with this tomato seedling?
Leaves are yellow with darker veins. I'm clueless, never had a problem before. the other seedlings seem fine. Drainage is good, so it's not over watering. Thanks, ed

I would hazard a guess that it is a nutrient deficiency. Looks like it has missed a few meals. What are you feeding it?

Had only given it a little diluted liquid MG. I just gave it a nitrogen infusion (Calcium Nitrate) with some stronger MG. Should darken in about 2 days if it did the trick. Thanks.

It looks like early Magnesium deficiency to me. You may want to try a light dose of Epsom salt diluted with water. It should come right back to life.

I would have said over watering but you say this can't be the case.
It didn't suffer from cold weather? It does look like magnesium deficiency but potting soil usually has enough nutrients and fertilizer for a couple of months (mine says +150 days). |

Thanks, yea, no cold weather, but there might be a bit of sun damage on one leaf, but that's not the problem. Correct, it's not overwatering. I thought of Mg, but like you say there's usually enough, and my other seedlings don't have the problem. Will give the epsom salts a try. Also thought it might the pH of my homemade mix, so I added a very small pinch of lime.

The seedling that is photo bombing the photo (bottom left), has signs of the same problem, just not as bad.
I don't know which nutrient it's missing. I pot up with Miracle Grow potting mix so I don't have to figure out what the plant is missing, just add water and light |

Looks like interveinal chlorosis, which is caused by mineral deficiencies, so magnesium deficiency would be a highly suspected. You can treat this with lowering the PH and leaching the soil with a thorough flushing with low PH water, and then adding a complete fert with micronutrients. All this info is plagiarized. I ain't this smart.

This. 1 tablespoon Epsom salt to 1 gallon water, water after it dries out a bit. It's going to green up in 2 days after.

Thanks, getting it more Mg. To be continued.

A little very diluted fish fert will fix it up.
