Dry leaf edges mean it's short of water.

Could your leaves also be scorched? I note that you have water or at least dew on your plants.

i live in central florida, so it gets ridicuously hot till about 2.. than the sky falls out with rain (as on image).. than hot again.. your saying it could possibly be like sunburn on a leaf?

Yes, it's sort of like sunburn. If there are water droplets on leaves during the hottest part of the day, the water will magnify the incoming sunlight ... just like a magnifying glass. As you can imagine, it gets pretty hot. From the weather you're describing it sounds like that may be an issue.

Agree that it isn't a disease it is just environmental damage with perhaps a bit of salt damage from fertilizers. What fertilizers are you using and how often.

Try less frequent but much deeper watering. Peppers are water-sensitive and don't like to be wet all the time. Of course you can't control the rain but you can control any supplemental watering you may be doing.

And for future reference if you find burned, crispy, lightly curled edges of leaves it usually means too much N not too little. Peppers are not nitrogen lovers so go easy on the fertilizers.

You might also what to explore the Florida Gardening forum here and ask about proper planting dates for your area. I can't tell for sure how large or old this plant is but I suspect it may have been planted a little late. But the Florida gardeners would know best.
