-coco perlite mix
-Canna A+B,Rhizo,cannazym
-tap water 7ph 125ppm
-ph always to 5.8-6.2
-ppm at 1100
Wierd burn/crispy spots on leaves

Looks like water spotting more than any deficiency. A couple good pics would be better than a video to get a better look.

Sorry for the long time not answering :/Looks like water spotting more than any deficiency. A couple good pics would be better than a video to get a better look.
The dwc setup has crispy leaves too. Not too sure whats wrong

Most likely your tap water is making things out of balance. You're at full strength A+B right?
Since every plant is showing issues the one common factor is the water they are drinking. I'm pretty sure you can find out whats in your tap water, search google.

The DWC setups are on GH gro,bloom and cal-mag, with a couple other additives then ph’d to 6.2
Maybe not enough light? Ill make a video tonight

No light issues will never do that to your leaves. Yellowing/burn closest parts to light if too close of lots of lanky pale growth with too little light.
That’s a nutrient problem. Have you tried using RO water?
Again, different set up and the only thing that’s the same is the water.. perhaps high levels of magnesium blocking calcium?
1100 ppm on which scale? Running 2.2 EC you have a higher salt concentration that will mess with your plants uptake in nutrients. You'll always see heavy feeders chase their tails correcting deficiency problems because they think pushing their plants to the max is advanced growing. Its not how that works. 1.7 EC is also on the high side. Nearly every strain I've run never needs more than 1.2.
My advice change res and lower your EC.

It's a calcium deficiency.
Cal and mag deficiencies are common with coco. Get some sort of cal/mag additive.
Good start otherwise

Looks like Mg actually. I posted this issue here last month about my heavy sativa and no one really pinned it down. I was already adding CalMg+ to my RO water and all other parameters were correct, I had other plants and different strains with no problems.
I went in a few days later with a 1 gallon sprayer with 1/2 tsp of Epsom salt and did a foliar spray and wet it top and bottom side and let it dry out for about 10-15 minutes (get lights up high so you don't burn leaves). I then did another 1/2 gallon spraying of just plain water. couple days later the issue was improving and no more twisted crispy new growth, other affected leaves were getting healthier minus the necrotic damage that is irreversible.

Dude great info! Ill give it a go
Cant post photos anymore apparently
need 2 likes now. Wierd.Added some nutes to the little guy that had burn spots. All the rest have normal strength nutes and kinda crispy leaves/twisting, going to give your salt idea a go.

By the way, mag deficiency looks more like this

The coco girls are looking okay. This is their feeding mixture, might try to change it today, they need a drink.

Dwc mixture:
Maybe the dwc girls are getting toasted. They look okay

Ahhhhh shes feeling it! Drop the ph way down to 5.5-5.8

Odd nobody commented on the PH right out of the gate.
Coco and perilite= soiless = 5.5-6.5 ph. OP said PH was near 7...
This is a mutli-nutrient lockout due to PH.
Just my noob 2 cents...
The first pictures look like very early stages so dial it in and they should recover quickly!

Flushed that one today with ~PH 5.9 water, guess that's still a bit high, but it's something. Finished with a weak solution of NPK 5-2-2, and a tiny pinch of calcium nitrate. Right now i'm only testing with that plant, it being the sickest.
There's obviously something wrong with the soil, runoff is always near 7 and won't drop. I was using the same exact label years back and it was top quality. Used up some of the leftovers from that time when i put my sprouts in solo cups. Second transplant was with the new stuff and a week later that one had spots on it, right now 5 plants are getting sick.
Got 2 stunted seedlings that are now growing and still in the cups. These give a 6.3 runoff, no problems there. Same soil, different year.
