tiny brown insects Could be spider mites/russet mites or aphids. (the dew you're describing suggests to aphids to me, though) Suggest you go here and look at the pics of Foliage Pests. Not sure about the "fungus" though based on your limited description (tiny black spots). You might want to go to the Tomato Problem Solver (link at bottom of this post), to see if that doesn't give you some help. If you could post a picture, that's helpful. tops of the plants are also curling. Could be mosaic virus, or curly top -- or could be related to the aphids (if that's what you have). Leaf curling can also be caused by environmental stress, and may not be a major cause for concern. So, have a look at some of the sites I've linked to. Will wait to hear back from you after you've done that, and we'll go from there. Here is a link that might be useful: tomato problem solver and other links

OK I'm back with more questions. I've been reading a lot today. One website says grey spite are botrytis blight. I hope I spelled that correctly. Lol.is that what this is? This is the same plant in the other photos when i ask if it was a disease.can it be saved?.i have lots of house plant but never heard of this diease.

Honestly, I think you're over reacting...in my experience splash plants virtually never revert to solid green...they may put out more lightly splashed leaves (look at your half-splashed leaf further down) or even no-splash leaves (like your two newbies) but the MAJORITY of their leaves will continue to be heavily splashed...You may be confusing the splash clone with the variegated clone--like Krimson Princess--which does seem to be quite unstable and will revert to solid green if you even look at it sideways, but the splash phenomenon seems to be very stable and, as I said, seemingly never totally reverts....Hang in there and watch for more new growth--chances are like 100% that the splash will be back :-)

Appears to be spider mites. Nasty critters. I've tried the high price mite poison. They damage the plant and the s mites will become ammuned after 2 apps and then you need a different one. Finally I found a good answer. Dishsoap. It must be the gentle type. Some are degreasers. Too strong. Ivory is good. 1 ounce to the gallon. Spray throughly, top and underside. Re-do in a week. Watch it it may need a third app. I think the spider mites are still active. Good luck
