Well the good thing is you've determined what the problem was. now all you have to do is find RKN resistant peppers until you can get them under control which is a long process but obtainable. Sadly you can expect to see a decline in all your plants that are susceptible until corrected because those little you know whats spread like wildfire in sandy soils. They are among one the worst thing to happen to a garden, but in FL there are more than a few bad pest that are on the top 5 list. With RKN having such a broad spectrum of host you should act as quickly as possible to get them under control. As your plants begin to suffer other pest will notice the stressed plants and can put them out of there misery or kick them while they are down. I hate to say it's a downward spiral but without acting quickly it is just that. If you have the money have a professional come out and determine what will be your best options. If you're poor like me there are many helpful links on the net and even some youtube videos out there that can give you some ideas on how to control them. Use several things in conjuction and only plant resistant varieties of plants for the time being. There are some hot and bell peppers that were bred here in SC that are resistant to RKN, Charleston bell I know is one of them but it may be hard to find. I have some friends that may have some extra seeds if you are interested, I can ask for some. Good luck and don't give up.
