Seedling problems

million · April 5, 2006

I am having problems with many of my tomato seedlings that I've never encountered before. The underside of the leaves are predominantly purple with the worst of the bunch having what appear to be purple spots as well as slight yellowing between the veins when you look from above. Upon closer inspection with a loop, the "spots" are more along the lines of purple droplets that have gathered ay the base of the hairs. To me, it doesn't look like any of the blight or spot diseases that I can find but I have never really encountered many problems with tomatoes firsthand. My eggplants and peppers are growing with the tomato seedlings and seem to be unaffected. I am in a different place than I was last year and the house stays on the cooler side. Because of this, I have noticed fairly slow growth as compared to other years but this is the only thing I can come up with as a possible cause. I did consider that it may be a phosphorus deficiency but fed one of the plants a high phosphorus food and over three days, it has not shown any real change. I'm a novice grower and still have a lot to learn. Any help is greatly appreciated. I grow heirloom varieties and I'd hate to lose these plants. Thanks!
