Got a late start and im in Kansas which experiences 95+ temps this time of year. Does this look like sun damage or something more serious? I have treated with 3 different anti-fungals and it looks to be spreading.   Thursday, September 2 View Page Looking for help. Have done all kinds of fungicide and insecticide. Leave edges yellow then brown. Recently changed to drip irrigation with fertilizer injector.   Thursday, September 2 View Page Another Picture of the leave issue. Found Aphids and beetle eggs 3 days ago.   Thursday, September 16 View Page Did soul test. Said I needed N and P add to soil and did foliage application. The center oldest part of the plant continues to die. I planted late and the dirt plot was a lot of different soil types. Heavy clay so I brought in a lot of composted cow manure and and top soil. We were living in Northern California until mid May so didn’t actually plant until June when we moved back to Kansas. I also switched to drip irrigation 6 weeks ago. Doing 3 hours a day of watering. Next year will do a lot more prep work
