I'm uploading a few photos of leaves on my plants. The photos show what angular leaf spot looks like, I'm 99.9% sure that's the correct diagnosis. Just FYI.

Maneb and copper sprays. I sprayed tonight, but then of course it rained afterwards.

Looking at your photos Kyle I would say you have a very common problem that occurs when growing in a plot with shallow cultivation, lots of moisture, and an excess of potassium (note green/blue soil), the binary plants that are binding up in your CEC level (grass) are also spreading the fungal desease to your plants leaves and roots. Solution lay off the # P # and bury/trench vines, extra watering may help, but in our experience the soil is so contaminated at the "moldy stage" that it is to late to correct as deep cultivation and watering is what is needed to correct the problem. Hope the rest of your plants are doing well.

Having seen more of those pics than posted, I'd agree Kyle has ALS on aq couple leaves.
Though some are not. Look at the wind broken leaf veins in a couple pictures. See where the necrotic areas are "south" of the vein breaks? This is nothing more than mechanical damage that looks angular since the veins radiate outward & sustain an angular area of leaf.
Sweat or spray tip drips appear to have caused a few of the leaf disorders. Fodder for another post I think. LOL

Not trying to step on ya toes steve,,but those little yellow spots and the holes are a dead give away..Leaf spot!! I've had it last 2 years..I've heard so many different stories..Soil borne,seed borne,and als air borne..Never the less,,it spreads by water droplets..Over head watering is a no no,,,it can be controlled Kyle..Hang in there bud..My 735 had it,,I kept it at bay this year,,unlike last year...

Gads....thanks for the info, extremely helpful, much appreciated. I wondered about that algae and its' cause. The grass you see is from my yard, I grow some plants there every year and they're dispensable should catastrophe hit. I can't do much about it however except spray well. But as far as shallow cultivation, my patches were ripped up pretty good right before planting, 18" or so. I have gone back and am slowly loosening things up to about 5-6", maybe 4". I'm not fertilizing at all really, a bit of Ironite but that's it. My compost is so nutrient rich, fertilizing is not needed, it would be excess. No additional "P" has been being added. This stuff is spreading pretty quick. Steve and I talked and I know what to do...but I need a few dry evenings. Spray and rain, spray and rain, spray and rain.....argghh. Thanks Jeff, I wondered about leaf spot as well but wasn't sure. Do I use the copper/ maneb sprays for it as well? Thanks guys, I appreciate the input.

Kick it's ass Southern, these plants always pose a challenge pushing them this time of year, hell your plants problem could be from anything, just kinda looked like a build up of "P" from the photo and grass loves "P" to spread it's lil buddies around!

I'm amazed all the compost Kylke added to his soil didn't keep that mucky soil open enough to drain. Calcine Clay next year in one hole Kyle. You owe it to yourself to try.
Mancozeb is labeled to kill algae at high rates if things get really ugly. Algae robs soils & roots of oxygen.
I wonder if this is why bleach.....?
