Orange brown splotches and yellowing leaves

I’m getting some wierd issues with my leaves. Lots of them were yellow near the bottom and I pruned them so there were more b4 the pic but I thought it might be natural. Now though I’m getting orange brown areas on some of the leaves not just the bottom but middle as well. Can someone suggest what I can do to fix it please? Everything seems ok to me as far as readings go so I’m clueless at this point.
5 gal fabric pot
Fox farm ocean forest soil grown outside
Tested run off of water using fresh opened gallon of distilled water.
Ppm 1133
Ph 6.5
Vegas nights 2 strain
Very hot n dry weather . Have to water 2x a day
Haven’t fed ina while bc fox farm soil has nutrients in it and leaves look pretty green.
Have given it humic acid/kelp, tea, cal mag and GROW fertilizer previously

Cut back nutes when hot: plant will uptake a lot more water when it’s hot and those salts ride along with the water.

Haven’t fed in months. Last thing given was a little cal mag on 6/8

I am new and still learning, sooo just my opinion. It looks like something is eating your leaves. Have you used any type of pest control?

Also, your plant looks very large. I don’t grow outside, but most of the outdoor grows I have seen are in much larger pots. Perhaps that’s why you have to water twice a day?

Any chance of it being root bound?

Any chance you left water droplets on your leaves after a watering? The water drops can act as a magnifying glass and burn holes in the leaves. I live in AZ and this happens on peoples lawns all the time, and in my tent when I use a sprayer to water vs a liquid transfer pump.

I always try to water from bottom but I guess it could have splashed. I’ll put a water droplet on a leaf in the sun tomorrow n see what happens

Nothing. Almost noon n super sunny n hot. Put 2 big drops on2 different leaves n nothing happened. So I really don’t think leaves that aren’t directly in line of sunlight would be turning orange

Could it be heat stress but on just one part of the plant? Or deficiency or excess or nutrients caused by hot dry temps? It’s been 100s out lately and it’s definitely not water on leaves in the sun.
