weird THING killing my plants >_<

hi guys, i posted a week or so ago about this weird thing that keeps happening to my little veggie garden. everything grows fine for a few months and then this happens. it seems to start in one spot and then radiate out. i've tried to cut off the diseased leaves to slow it from spreading and that seems to help but is there any way of stopping it completely? and what the heck is it anyway? i got some nice watermelons out these plants so i'm not completely sad. but i just couldn't stop the spread of whatever this is so i've completely cleared my garden out today (the baby watermelons seemed to be rotting on the ends and splitting open). it is totally naked now and i could also use some advice as to what veggies and fruits are good to start up now in northwest florida. any ideas are greatly appreciated! -todrik
