There is a super high res deficiency chart in the link in my signature
Medium:
Coco + perlite 50/50 (3 plants)
AND
Coco + perlite + peat moss 30/30/30 (4 plants * THE 1 IN PIC *)
Using RO water (20ppm).. comes from tap does RO effect whether the water is hard or soft or does the filtration not change this?
I'm growing multiple strains (I know not a good idea especially for beginner). So I'm only going to be running plain PH water on the 2 showing this deficiency OR should I just do so on every plant UNLESS tip burn is not an issue? Can no explain the 1000-1600ppm general guidelines from the screenshot above?
I grow in coco indoors, my tap water is from a well - a pretty steady PH 5.4 / 250ppm TDS. That was sorta why Coco is just easier for me. You need to use a calcium supplement (I use Botanicare Cal-Mag plus, sparingly as it gooses the N just a bit). I happen to use the regular Canna line - and I use their online calculator for to set light, normal and heavy feeding. I mix 4 gallons at a time since I have to tweak the formula for whatever I'm feeding depending on stage and observed needs of the strain. And different strains have different "happy" appearances. I usually check my mix with the Blue lab truncheon, just after I set the PH at 6.1. I use the root enzyme and root tonic as well. You can also use the root tonic in a power cloner.
from the photos - salt deposition on the ends is probably from missing feedings and letting the coco get too dry, or excessive transpiration (heat sources?) that pull lots of water (and nutrients) to the leaf and dump the salts there. Also a sort of clue the nutrient levels may be too much for this strain.
You need to apply nutrient until you get some runoff. If you never get runoff, then this could be salt buildup if you've been over-enthusiastic with the nutrients.
Otherwise, if the color rendition is right, appears almost like too much heat, overall. Starting to curl up ( Cupping ). If your light source is significant (1kw or more) and emitting strongly in near infrared , too close?
Usually, I see the girls curl their toes a bit after a too strong feeding ( downward tip curl ). That means chill it a bit on the nutrient concentrations.
Take a picture of the main stem also

And I'm adding perlite to the pots I know roots died from exposure
Thank you! Great info! Yes I just started charging my coco don't believe I did for that girl there can you tell me why 6.1 ph? I usually let it slide around whereever it falls between 5.8-6.2... And yes regarding the N in cal mag I was told not too use it in flower should I use very small amount say every other feeding?I grow in coco indoors, my tap water is from a well - a pretty steady PH 5.4 / 250ppm TDS.

Usually, I see the girls curl their toes a bit after a too strong feeding ( downward tip curl ). That means chill it a bit on the nutrient concentrations. I back it off, usually preemptively by feeding again sooner with a somewhat lighter mix ( to a nice margin of runoff ) and the curl goes away in hours if I did it early in the day. Then I make a note about that strain. I usually run multiple of the same, so I can see it is indeed a strain reaction. And indeed, this is one of the hardest things to find out about, unless you just grow a strain - and watch her the whole cycle. You can find all kinds of genetics charts and associations and musing about what a strain would might expect, based on its heritage. I've found it all less useful than just growing it and figuring it out myself for the most part unless I can find local growers that know the strain I'm working with.
