Help needed with leaf diagnosis

I have this going on with several plants. It maybe sun burn from canola spray. Too much langbeinite? Any suggestions appreciated.

Looks like it could be a sulfur issue causing a lock out. Is it getting worse. How’s the rain been could’ve went through a dry spell also with how shits been lately I’ve had a few outside plants get real dry then get rained out then get super hot all within a few hours and it has them
Looking weird. But if you look at a leaf chart the leaf discoloration looks like the sulfur problems on the chart.

It's hard to say if it's too much anything without knowing what you're using and how much. How did cooking spray get on your..... nevermind. I don't want to know lol. What is the soil and what have you been feeding it? Then hopefully we'll figure out what is going on. It looks like something got on the leaves as opposed to a nutrient issue but let's start at the soil and nutes if any

The canola spray was …. for ?
want non stick leaves ? …… confused and high

Thanks for the replies…
firstly, the canola oil is the base used in a commercial insecticide containing pyrethrin and sold over the counter. It was sprayed on heavily with a hose end sprayer in the middle of a hot day
Interesting about the sulfur. I did add some fast acting sulfur to the soil this year , first time using it, to help lower ph and because I read sulfur is beneficial to flower smell.
I usually prepare my soil using bulk organics but this year I didn’t, so I’ve been adding so much crap to the soil trying to get them back on point is a challenge.
Again, thanks for any light to shed.
Ph is good currently around 6.5, , moved down from 7.0.

You burned her never spray any thing in the middle of a hot day should be fine live an learn.
