K deficiencies, Texas Heat Wave After math, and Champanel

[Lando545]

In Texas, I've finally gotten a break in the Hot weather and my vines can start photosynthesizing again after almost 2 months of unbearable heat. My Concord, Cayuga, and Flame Seedless are showing signs of what I think are Low K levels. My Champanel however really performed for me in the heat. They handled it extremely well and aren't really showing signs of any type of Deficiency like the other varieties are. They also handled the drought well too. I Have not had any disease or fungal pressures yet. The insect damage wasn't that bad this year. I think all I had was some minor leaf roller/Skeltonizer damage which I took care with some Diatomaceous earth I hope. An extremely late frost took all of my harvests this year, and then we rolled into this heatwave, but overall I think I'm doing well and hopefully I'll get some grapes next season.

P.S. my image files were too big so ill be posting an Imgur link.
