Might just be from early season weather swings. None of my tomato plants look very good until they really get going with the good weather. Sorry I wasn't much help.

From the pics it looks like all the damage is on the old leaves and the new growth looks fine. Correct? If so then I'd call it environmental damage just as thousands are having this year because of the unusual spring weather problems and too early planting.

It is still too early for planting out peppers down here given the soil temps. They are running 20 degrees below normal from all the heavy spring rains and the cool nights that ran several weeks past normal.

So how long have these been in the ground exposed to unusual weather?

got some good mushroom soil

Often very low in nutrients. What have they been fed?

Hi Dave, i fed them Tomato tone. That is usually the only thing i use. Do you recommend anything else? They have been planted for 1 week. The banana peppers have brown spots on the leaves, but the new growth does look good.
Of the 15 tomato plants i have, only 3 of them look to be crappy looking, all the other 12 look great, so that is why the concern.

For some reason when i catch those brown bacterial spots on my peppers, i have trouble beating them back, and i've used every chemical under the sun. Some work better, some don't. It isn't the worst thing they can catch, but it is contagious btw.

For more generic plant varieties, i would just yank them out, then buy more and plant those instead, it's early enough in the season. If it's a rare type of plant, then i'll baby it and spray it down with one or two different solutions.

Those May temperature fluctuations + cold rain will get you every time. This is why i prefer to plant out later than normal, instead of trying to beat mother nature ;)

Keep the leaves as dry as you can, but seriously consider yanking a few of the worst, and replant.
