Diagnose these leaves (PICS that are in focus)

These were taken from a room of a group of some really awesome caregivers I had a chance to meet, down in CA. I took a bunch of pics - here is a small amount of them.

At first I thought heat stress, but some of these pics are taken from leaves in the shade. The first picture is more accurate in color - some of the photos are washed out a bit.
Temps 78-80
humid 50 +-10
1000w ( I think) 2-3weeks in bloom

Check out this link and see if you can find your answer there. Most problems I see ppl ask about on here can be solved by reading this thread or another one by uncle ben. https://www.rollitup.org/marijuana-plant-problems/150004-plant-moisture-stress-symptoms-solutions.html?highlight=uncle+ben's+plant

if the above link didn't help ya here's a link to all of uncle bens threads, he really knows his shit so this should help ya identify the problem and solve it. https://www.rollitup.org/search.php?searchid=9995616

That last link didn't work - and I'm not sure what problems are in these pics, it's hard to tell with those text guides.

Anyone else have experience with seeing leaves like these?

Here are some better pictures. Keep in mind the leaves are deep green - doesn't look like it in the pics.

looks like a ph problem or micro defieciency from lock-out... just my 2cents

PH is where it should be. Lockout of which nutrient? Lockout caused by what?

too much of any one nutrient can cause the lockout of another. Basically the plant takes what it needs and leaves the rest if it accumulates too much it will lock out other nutrients. Its hard to say but it looks like a micronutrient def. somewhere. I would just lay off nutes until problem went away They don't look that bad.....

mmm ok.
anyone else?
