Eggplant and pepper leaves curly/misshapen

Hi guys,

I am having a tough time figuring out what is the problem with my eggplants and peppers and I hoped for some help. This is the first year I am growing these plants and after I planted them outside, they started to grow curly/misshapen leaves. Leaves seem healthy, no spots or anything, plants seem to grow well enough (forming blooms, getting new leaves...), but their leaves are not healthy looking at all.

All other plants (cucumbers, squash, salads, strawberries) grow well in same soil and have no misshapen leaves. It is the second year I use this soil and it was a mix of my own compost and garden soil. I used standard fertilizer two times this year, carefully with dose and I also measured ph of the soil, which is perfectly neutral (but I still tried to add some calcium and magnesium, maybe they lack them?). The only additional chemical I used was anti slugs drops, could these be the culprits? I am pretty lost...

My tomatoes are like that and after googling it to death and coming up with no answers, I've decided it must be the horse manure I got from a local horse farm and tilled in before planting. It's a new bed with no chemicals or fertilizers and the manure was over a year old. Oddly, the Brandywines are just fine with no leaf curl. One possibility for leaf curl is a virus, but if that were the case the plants should have died by now. I figure as long as they are still alive, growing and setting fruit I'll just roll with it. They look funky and are obviously stressed for some reason, but a little stress supposedly results in better tasting fruit. If that's the case I'll have awesome tomatoes and you'll have awesome peppers!

I'm having the same issue with my rudbeckia and rhododendron.  I've put no new inputs into either of the beds involved.  I chalked it up to a virus and removed the leaves as I came across them.  The rudbeckia seems to have recovered, but it's come back a bit on the rhododendron.  Do all viruses kill plants, or is it like with humans, that viruses are troublesome but not necessarily fatal?
