Yellowing/wilting outdoors. Are these gals done for?

Hey all. Doing a small guerilla grow this year in a woods line between cornfields. Plants are from seeds of the crop I grew last year and they're in ground in super soil/native soil. Throughout veg plants were fed ff grow big 1-2x month along with a couple top dressings of happy frog all-purp 5-5-5 and recently I applied Jamaican bat guano as a top dress and fed tiger bloom for the first time. So anyway,plants were off to a good healthy start with no issues until now. 2 plants are wilting and dying rapidly. I've watered the 2 plants 5 gal per day the last 2 days and appears things are only getting worse. Is there any hope for these little ladies? Any thoughts on what's going on or any advice is much appreciated

Unfortunutaly I've seen this happen a lot this season and last. Usually it's been traced back to an infection in the stem and root system. Like heart disease, the plants rot from the inside out and then suddenly decline and die. Possiblely fusarium mold as the cause.

Seems to me being in the native soil probably stays pretty wet around the area...I would only be watering plants that size about a gallon of two unless they seemed to be needing it from heat...root rot my friend, they won't intake anything anymore ....best thing is to pull them ASAP and plant them in some dryer soil ..not dry dry but let them gain some root growth back. .at this stage I have had to much experience and would say bye bye lovely ladies though. ...careful on the water my friend...that soil looks well moist without anything...I have plants that have had roots reach 20 feet alone and only would water them when you stick you finger in the soil and after an inch you don't feel moister..good luck my friend!

Thanks fellas. Glad to get some useful input
