Are you saying there is in abundance of calcium because the plants aren't using it due to the ph being below 6.0 which is locking out magnesium causing the rust spots?

Moisture on the leaves is exactly what I'm talking about. You want to avoid having the plants touch. Maybe get a fan with a lower speed.
I think your ph should be climbing not dropping. How do your roots look? Growing media can cause acidic drops, Bacterial or fungal root infection causes root decomposition. Bacteria generate organic acids and acidify the solution.

Im saying the plants cant take in calcium with the ph so low and you need calcium to absorb magnesium. I could have it backwards I need more coffee
I'll take a look at the roots. For a while there my plants were stretching and acting funny and I realized the roots were trying to grow only between the two buckets so I placed growpots inside the upper bucket to hold the roots inside the top bucket

you should give me a whole run down of whats up i am a very well dialed in hydro guru you can say. i used and dwc drip ebb aero all em and know the problems running into
Just checked night time temps and controller read 64 degrees and humidity at 70 
. Can't have cool Ac without added humidity I guess. I turned up the Ac to 73 degrees from 70 degrees to see if I can meet in the middle. Previously was set to 75
Edit:
So if things don't get better we can rule out temps (Ac) and fan since I'm getting a second fan setup on the other side of the tent soon

AC removes moisture from the air, so humidity should be kind of low.
I changed the settings on the mini split to dry (dehumidify) and temps are 64 and humidity is 59% I'm gonna try and get the temp up a little and humidity lower (around 50%) over the next day or two. I'm hoping that when I move the temp up it doesn't allow the humidity to go up with it but we'll see.
Anyone know how exactly you hook a dehumidifier to a controller since they both try and set and adjust humidity by turning on and off? Right now I have the dehumidifier plugged into the wall but id like it on the controller of possible

if it works on its own, I'd leave it, however I think I see what you mean. your dehumidifier won't come on in relation to the humidity level. does the controller have an outlet you can plug the the dehumidifier into? 59% is better than 70%. it'll be interesting to see how this works out. humid air is considerably warmer than dry air as the liquid conveys heat energy more easily than dry air. I think 70 degrees F and 40-50% is ideal but I wouldn't struggle with it; just do the best you can and you'll probably be okay. I still don't know for sure if temp is the problem, but that discoloration and your use of the word crispy makes me think that this is largely heat related.

the crispy sounds like leaf condensation and then light burn it has tobe very common problem add circulation fans

a lower temp should lower your humidity some. give it a try and see what happens. report back here so we know.

i noticed with my ac putting it on 68 it kept kicking on and the condenser sucked the water out because it was always being kicked on,not just on standby with the fan blowing until it hits high temps because then the humidity is way to much.

You said you were checking the roots could you take a picture?
Omg gosh I just checked the roots and my buckets were bone dry under neath which made me start looking and the damn fill plug on my controller bucket came unplugged. I'm trying to remember how many days ago that was. SHITT!!!

Brown is not good and probably the root of your problem. Any body see what I did? Anybody?
Floranova always stains my roots but I've always had this problem so maybe you're right.
I'm giving them a good soaking and I started thinking about it it could have only been a day maybe two because I record how much water the plants drink a day too.
