Would it help misting them we live in the high desert he waters them every 3 days but they have been like this for a few months
How do I do what you said?
Normally don’t recommend misty anything anytime unless it’s for treatment of bugs. Best bet is to fill out that ticket cause that will give the pros exactly want they need to offer the best advice

Too many nutrients… there burning up… 
I would recommend a flush with just plain water and find out what the ppm of the water is before you use it and take ppm readings from the runoff of the flush…
Then you will know how many ppm you have in those buckets…
Thank ya sir!
Also if your concerned about outside temps , put some shade cloth over them … I’ve grown plants outdoors in temps that were over 100 + degrees , without shade cloth and they never looked like that…
Also , you never want to spray your plants with anything during daylight… you can have misters set up around the area in veg to keep breeze temps down , but dont actually mist the plants…
Peachy and Jbum gotcha. Give’m some shade. Temps prolly off the charts. Check those ppms as well. Do you own a tds/ec/ppm meter thingy? The runoff numbers there would be helpful
That swing could be a thing too. 40° with a 40 swing is tough. I’d have them on some sort of heating blanket under a foam pad to keep those roots warm at night.
