gee looks like early blight to me on those spuds, my experience is no amount of copper sulfate or other nasty chemicals will help the spuds now. we get this problem here on the wet coast and planting very early and harvest early is the best strategy,,,,, as for the tomatoes, they have to be kept out of the rain here, we have lots of heat units but we have to keep those tomato leaves dry. my guess is the tomato plants will out grow this as your summer arrives, i often snip off and destroy infected leaves, ofcourse some varieties have more resistance,,,, if your spuds die down, enjoy those early nugget potatoes, mmmmmmm

I wonder if part of the problem might be that there is more than one ppm scale and how do you know which one is being quoted? One ppm scale is the EC X 700 and the other is the EC X 500. That could be a pretty drastic difference at 1000 ppm. I'm growing some cuc seedlings and they are just putting out the first true leaves. I started them in a weak nutrient of about 4-6 CF. I have slowly brought it up so that now I'm around about 12 CF. This is around 600 to 840 ppm (depending on scale) and the seedlings still seem ok. Granted it has been raining a bit so they are getting some fresh water rinse as it is an outdoor system. I'm guessing that part of the trick is to adjust the levels slowly so the seedlings have time to adjust and if there is an adverse reaction you have time to react before killing the babies. One thing I'm noticing about the cucumbers is that they are not the fastest off the mark. My squash and zucchini are so far ahead of the cucs even thought the seed packet give the same time to maturity for the cucs and zuccs I don't believe them at the moment.

Jo, Those poor babies are beyond sad. Like Jay, I'm going with a gut feeling that they are starving to death and are suffering from multiple nutritional deficiencies. I think that Marcy got the nutrient deficiencies identified exactly right, but I'm also concerned they're lacking micronutrients. I suspect there is something really wrong with the soil in those pots, but I don't necessarily know what it is. It could be she used regular garden soil dug out of the ground, which is a big no-no. Or, she may have used a 'cheap' bagged potting soil which has a heavy clay content and which drains slowly. If she tells you that her soil stays wet all the time, then I think there's a poor soil/drainage issue. The excess moisture clogs the roots so they cannot take up nutrients in the normal manner. That's why the foliage is so discolored and you see the purple veins. I'd foliar feed, alternating between Miracle Grow and Liguid Seaweed. I'd top dress with Espoma Tomato Tone too, following the package directions. If you have received more info on how they're being grown, please share it with us. I also think they look really leggy, so suspect they may not be getting enough sunlight. Either that, or so much is wrong nutritionally that the plants are not conducting photosynthesis in the normal manner. Jo, I don't know if feeding them will save them. They are so sad-looking. However, the fact that a tomato has set gives me hope that she can turn them around and turn them into productive plants. Dawn

I cut through the black discoloration in the worst looking stem, the inside was green (looked normal). It looks like the black does not go all the way though. Right after I planted out we had a few foggy damp mornings, cooler but not cold by any means. The spots showed up right after that. So far it hasn't spread to any new plants other than the ones it first showed up on. I mulched them with straw right after planting but probably need to add some more. I'm trying to decide if it would be best to just pull the bad plants up and start over while I still can. I hate to do it, since these were heirlooms I special ordered and I probably won't be able to find more of those particular varieties. I only planted one of each variety - I wanted to try as many as possible! I really hope it's not something that's in my soil now that would infect the new plants if I do replace them. I sprayed with Daconil right after the sports showed up (too late for the ones that already had it I think). Maybe that kept it from spreading? I am going to try the copper spray tomorrow.
