Leaf curling alone is a physiological condition caused by stress; it's common in stressed plants, including young plants which don't have the root system to support all their foliage yet, or in times of unusually bright sunlight. If you get it by itself, look to see what may have stressed the plant recently; often it's nothing to worry about. The wilting, dead green leaves symptom resembles bacterial wilt, but that's pretty rare in your neck of the woods, and tends to take the whole plant down very rapidly. Stem borers can sometimes do it; look for little holes in the affected stems. Look for any damage to the stem, in fact. With the yellowing and necrosis -- it's hard to see in that small a photo, but it looks like the dark lesions are following the veins. That's diagnostic of a toxin of some kind -- no virus I know of does that in tomato, no bacterium or fungus is that specific, and no deficiency kills the veins before the interveinal spaces. I've seen a symptom almost identical to that in a case of alcohol poisoning (someone had a cocktail party in a library foyer and apparently the drinks weren't very good, as the potted plants looked pretty rough afterward). It was an unusual enough symptom that it became a teaching example. Toxins can come from outside or from the soil. Pyola is perfectly safe for tomatoes, and the heat wasn't excessive, but make sure the dilution was correct, as too high a concentration can burn leaves much like that. Spray damage can also cause wilted and dead green leaves. If you can sacrifice a plant that's badly affected, dig it up to look at the roots, see whether it has lots of crisp, white, fine roots, not dark or knobby ones. Shave away the skin at the soil line to look for discolorations in the woody stem underneath; cut open wilted green shoots to check for hollow centers from stem borers; and finally split open the main stem to see whether it's hollow or discolored inside. I don't expect much except maybe root symptoms, but you really never know. My personal guess is soil toxicity, especially given that the lower and terminal leaves are the worst affected by the yellowing and dying, and some things take a while to build up in the leaves enough to kill them. One important thing to note is that not all toxins are synthetic chemicals -- an excess of certain minerals or nutrients can poison a plant. pH affects root uptake of anything enormously, especially minerals, but it can have its own effect as well. You may need a soil test -- call your Agriculture Department, Cooperative Extension, or U of O to find an affordable lab. I don't see your symptoms in any of the common nutrient toxicity listings, though, which means it could be something chemical, and there is no general panel for that. Down here in California I'd send it to Sacramento's Plant Diagnostics lab or the extension pathologist at U. C. Davis, but I don't know what pathologists you have at your disposal. This is certainly not a cut-and-dried common disease problem, and even a specialist is going to need some lab work to figure it out, I suspect. I wish I had more answers for you, sorry. --Alison

bacterial speck, maybe?

1) the spots at this time look more like some kind of mechanical damage, wind/cold burn/pollution or edema that has likely since passed. If that's what it is there is no need to spray fungicide and there is nothing you can do about it at this point. Only one picture I saw looks much like fungal spots. 2) the plants are in need of phosphorus (purpling). Unless you use something like bat guano tea very few organic sources will be able to get enough P to them quickly. If you use a high P amount liquid "bloom" fertilizer they will not look like that in about 5 days.

So I've been growing some beefsteak (I think) tomato plants indoors, mainly for fun, but I do want them to do well. They've seemed to develop some leaf curl, and those leaves have gotten kinda bumpy, like they're crinkling up almost, along with yellow-ish spots? Sorta along the veins on the leaf. The newest growth they have seems to be unaffected, but I don't know if it'll stay that way. I've tried researching what this is but nothing I've seen looks exactly like this? Not sure. If anyone could help me out that'd be very nice! - If it helps, they're under a LED growlight in a windowsill that doesn't get much direct sunlight. I just transplanted them into bigger containers (solo cups with holes in the bottom lol. Couldn't find actual pots to buy, but these are temp.) I put them in a mix of Miracle-Gro potting mix & ecoscraps natural + organic potting mix. Thier two first true leaves were getting a bit yellow before I moved them, but I chocked that up to me not being able to transplant them fast enough, I had grown them in cut up egg carton and they got much too big for it and I couldn't move them right away. They seemed to grow fine after that though, and they're still growing. Also I didn't take them out of the egg carton because they had grown into the bottom of it a bit, so I just cut off what I could without touching the roots and stuck them in there with it.
