Hello! I've noticed some brown spots on some of my leaves, localized to one half of the plant. Any ideas what this could be?

what do you guys think this is ?
Hi Guys Sorry to keep bothering you all but please see the pics the leaves are curling downwards and going this colour. temps are high at the moment but seems like an overfeed to me. Curruntly flushing with just 5.8 water for 5 days then will re introduce feed.

Brown spots on leaves. Can this be because of too high pH of the water (7.5)?

2 out of 5 plants are showing signs of nutrient burn? Soil grow
Hi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz. Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.😦

I water with 50% distilled and 50% rain OR 50% distilled and 50% tap. I have fed once with Grow Big and it happened right after. Might have rubbed nozzle on the underside of the leaves. I water every 2-3 days and water until drop of runoff appears in tray. How much runoff?

What is this brown spot?
What is this brown spot? 18” from light. Just fed about 10 hours ago with dr.Earth 1-1-1 liquid solution watered in with 1/4 gallon of water. It is the only spot on whole plant. I know the temps are high. Wondering if it could be something else.

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?
First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

Deficiencies while in late flowering during flushing period
There is deficiency going on (looks like cal) she is an auto flowering strain in her 9th week and been flushed for a week now. Should I give her cal/mag and stop the flushing or is it too late to deal with that? She looks like she will be ready to chop in a week or so.

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐
