Help! Should I be concerned?
From what I can tell, the big center leaf looks like it might have powdery mildew. I've only heard about it, but I believe I read somewhere that spraying lightly with any kind of milk will clear it up. Also, watch what time of day you're wetting the leaves, if you're top watering. Best to do it before the sun comes up, or in the early evening. Not at night in your humid climate, cause the humidity is a breeding ground for the mildew.
Think "MILDEW"...
The little cluster of leaves to the right of your date concerns me. Those squiggly lines are leaf miners. They are inside of and burrow through your leaves, and mess with your plants. I've been tearing off the squiggly line pieces where I can. If it's too much, I just take off the whole leaf. Hoping to keep them in check before they infect my whole tomato crop.

It is indeed powdery mildew, the bane of warm, high humidity southern gardeners. I've used milk with only mild success. You can mix and use the instant cheap store brand too. From what I've read (mostly studies done in Australia) the primary way it works is by blocking sunlight which then inhibits photosynthesis. The problem with milk sprays is you have to spray almost daily to get it to work. Even then I'm not sure how effective it is after mildew is established.
After numerous failed organic solutions I resorted to Daconil for mildew and other problems years ago. This is repeatedly the one product I have seen otherwise organic gardeners go to. I solely use organic pesticides (and delay even those applications by using row covers until plants are well established) but there is nothing I know of after forty-some years of veggie growing that is organic and reliable.
teaspoon of clorox per pint of water in a sprayer in the mornings if you can live with that sort of thing! Place it on as fine a mist possible and don't saturate.
