What are my issues

Autopots can be troublesome at times. I'd guess that salts are building up in the medium. I've seen issues with these systems before where the top, drier section of medium is at a completely different pH than the bottom due to salt buildups and vastly different moisture levels throughout the pot.
Not a knock against autopots, I have seen some top tier grows using them. On the other hand everyone I know has had to top water to considerable runoff weekly with their autopots otherwise pH drifts and lockout rears its ugly head.

Please don't listen to this.
Why?
500ppm total? Look at the plants, they are starved.
After adding calmag to RO the PPM should be 250. So yeah, 500 total isn't enough.
The problem here is that people keep saying to run the ferts at half strength because 'the companies just trying to make money"
But look at those pics. They are yellow, off color and damaged. OP has apparently tried everything except feeding at the recommended dosage. Maybe he should try that? Maybe?

He's already tried to increase the EC with no effect.
You must have missed the part where he said they were in autopots. The plants are most likely locked out from nutrient buildup. Throwing more at it isn't going to correct it, it's going to make it worse.

They do look hungry... 500 ppm is not enough if you have a good light. I feed at 1000 ppm from clones, and climb up to 1200-1400 during mid flower, and feed every single time. No "plain water" breaks. Maybe you need to flush them at 1000ppm, and then give it time to see if the new growth is healthier looking. Also, make sure your PH is on point with the flush.

You don't need to feed heavy at all with coco. Are you just making stuff up as you go?

I maxed out at 600ppm my last grow under a great light. They turned out great.
Lockout can show the same symptoms as a hungry plant.

You going to handfeed to significant runoff one at 1.2 EC @ 6.0 and use higher EC autopot for the other?
I could do this post it we could consider it the thunder dome we can call it the grow room one enters one dies
Well I've been growing in coco for years so no, I'm not making stuff up. 600ppm is not enough. I've run that low before and my plants looked exactly like the ones in the picture.
At this point the OP had nothing to lose by increasing the feeding.
Should be around 900 in veg calmag included.
Alright got home today re tested all my shit and got these pictures from ec ppm and ph readings from res and auto pot these are no bullshit readings not altered in any way straight home and checked on them I did not remove plants from auto pot I know I know…. watered about six quarts into each pot from top vacuumed out auto pot res part where float valve is located about three gallons into my five gallon shop vac let’s see what happens in a few days if no change then I will go to the transplant and hand water to waste method I do for this auto in air pots which I’m leaning toward I just don’t have the time to fuck with them tonight my Friday there should be some change in color if not then it’s transplant time

830 is getting there but u gotta be patient. U aren't gonna see improvements overnight, the leaves that are discolored will stay like that and probably get worse. U wanna be checking on the new growth.
Def in the future do water to waste. U don't get the lockout issues. Its easy enough to set up a resevoir and a pump/lines so u aren't hand watering.

I think the lack of runoff is the biggest factor to the required PPM dosage. I'm using blumats and noticed that after I stopped hand watering every few days the plants developed burnt tips. My plants are three weeks into flower and I've been feeding them 600ppm all the way through. I'm also giving my bonsai mothers the same water and they are fine. They are tiny in comparison, but they are in rockwool and hand watered, so there's plenty of runoff.
Also not all nutrient lines are created equal. Some require a higher PPM. I'm using jacks now and it seems to be much more concentrated than say Canna Coco AB. I could max out around 1200ppm with Canna, but I don't see anyone going that high with Jack's. Most people say they run 900pmm at most.

Underfed yellow leaves will green up if the situation is underfeeding, they definitely shouldn't get worse. Nutrient burnt or other necrotic leaves will not repair themselves.
Locked out plants will worsened when you raise the EC.
