The first and the last pictures look like [Tobacco Mosaic Virus][6] (TMV). The mottling looks like it matches. The others, I'm not sure, but they could just need more of the right nutrients, and they may have a fungal infection. It may be too early to tell for sure what's wrong with those. I don't know if they also have a virus. Alternately, it could be [Tomato Yellow Leaf Curl virus][5] (TYLCV). Although peppers can carry this virus, I don't know if they normally have symptoms. Here are some links to pictures that led me to believe Tobacco Mosaic Virus was likely the case for the first and last pictures: * [Tobacco Mosaic Virus on a tomato][3] (1) * [Tobacco Mosaic Virus on a tomato][1] (2) * [Tobacco Mosaic Virus on a pepper][2] I might recommend planting resistant varieties next year. I don't know of any particular treatment for this year. Varieties resistant to Tobacco Mosaic Virus that I recommend looking into include these: * Yolo Wonder pepper * California Wonder 300 TMV pepper * [Capistrano pepper][9] * [Keystone Resistant pepper][10] * [Pimento pepper][11] * Chef's Choice Orange F1 tomato (also resists anthracnose; AAS award) * Chef's Choice Pink F1 tomato (also resists anthracnose; AAS award) * Big Pick tomato (probably an F1) * Celebrity F1 tomato * President tomato (probably an F1) * Park's Extra Early tomato F1 Reason for suspecting tomato yellow leaf curl virus: * [Tomato Yellow Leaf Curl Virus pictures][4] [Here are some varieties reported to be resistant to Tomato Yellow Leaf Curl Virus:][7] * Champion 11 F1 tomato * Margo F1 tomato * Sun King F1 tomato * [SecuriTY 28 F1 tomato][8] [1]: http://universityofillinoisplantclinic.blogspot.com/2011/07/few-tomato-diseases-seen-at-u-of-i.html [2]: http://ushotstuff.com/TobaccoMosaicVirus.htm [3]: http://0.tqn.com/w/experts/Growing-Vegetables-740/2009/07/TOMATO-CHANGES.jpg [4]: http://www.tomatoville.com/showthread.php?t=23714 [5]: https://en.wikipedia.org/wiki/Tomato_yellow_leaf_curl_virus [6]: https://en.wikipedia.org/wiki/Tobacco_mosaic_virus [7]: http://forums.gardenweb.com/discussions/2168124/has-anyone-grown-these-varieties-for-tylcv-resistance [8]: https://www.harrisseeds.com/storefront/t-Harris-Seeds-South-Tomato-Pepper.aspx [9]: http://www.timeless-tomatoes.com/capistrano.html [10]: http://www.timeless-tomatoes.com/keystone-resistant.html [11]: http://www.timeless-tomatoes.com/pimento.html
