| Hi, I've been growing my own tomato seedlings for 30 years, but I've never seen this before. A few weeks ago I started seeds for Better Boys, Sungolds and Super Sweet 100's. All germinated fine and all are growing quite well. But every single one of my Super Sweet 100 seedlings have yellow spots/stripes that remind me of some kind of virus. These are Burpee seeds packaged for 2013. All are grown in Promix, under lights in a constant temperature of roughly 75 F. None of the Sungolds or Better Boys have this spotting. But all of the Sweet 100s have it. I've looked under the leaves and see no evidence of insects. Hopefully the photo is attached. |

| How weird. Don't think I have ever seen anything quite like it, almost a variegated leaf as one might see on a philadrendon. Or a tiny teetotaler leaf miner perhaps. :) I honestly don't think it is a virus. The plants appear too healthy otherwise and even the affected leaflets appear healthy otherwise. And at least from the photo it only appears to be the terminal leaflets on the branch, right? That makes me suspect some sort of nutrient deficient issue at leaf development time or something genetically related to the variety. Though I have grown Sweet 100s and never noted it. But this is all just a guess on my part. I'd be inclined to isolate them from the other plants and just monitor them. If all the new growth appears normal then I wouldn't worry about it overly much. Maybe Carolyn or Darrell might have some better ideas. I'd be interested to hear their opinions. Dave |

| The spotting/striping is mostly on the terminal leaf, although there is a little on the other leaves. They're still looking good, other than these marks. |

| Do any of the pale spots cross leaf veins? |

| The leaf spots don't cross veins. |
