Its very def in K. When plants are not taking up K they have no defence against disease and this is what happening to your plants.
I think its a ph/ feeding issue you need to fix asap. Maybe foliar feed with potash liquid.
Those sick ones will struggle to come back.

there lacking in calcium and magnesium and need some calmag
they don't look over fertilized
whats your medium?
what fertilizers?
most of the time 1/4 tsp Epsom salt per gallon and 3 to 6mls calmag per gallon every or every other watering depending on your source water and fertilizer medium or soil type
first you can spray them a couple times with 1/2 tsp Epsom salt
second you might spray them one time with 4mls calmag
but do them separately to be cautious and space them out 3 days between
maybe; Epsom on Monday, calmag on wednesday Epsom again on Friday

they do look hungry over all
just don't go and over fertilize them and make what is a mild issue a big problem
tell us about your fertilizer so we can help figure out an appropriate amount... don't rely on the instructions on the bottle !! its almost always too much!!
brand of fertilizer and the npk% numbers
how you mix it currently

Sensi A Grow- NPK 2-0-0- 5 ml per gallon
Sensi B Grow- NPK 1-2-6- 5 ml per gallon
Neptunes Fish and Seaweed- NPK 2-3-1- 2ml per gallon
CalMag- NPK 2-0-0- 5ml per gallon
Silica Blast- NPK 0-0-0.5- 5 ml per gallon
Superthrive- 1 ml per gallon
I usually add 7-8 gallons of nutrients and add water til i get to my desired ppm. I then ph balance it to 5.6-5.8 somewhere inbetween that because it goes up over the days.
I am using Autopots in 100% coco with an inch of hydroton on the bottom.
I think i am going to stop using the self feed and just hand feed the plants from now on. I dont like this system. The other half of my plants are 2 weeks behind and they are in fox farms soil. they are looking amazing

mix for veg
part A 8mls
part B 8mls
Neptune 2mls is fine
silica 5 to 10mls is good (depending on your ph)
to determine the amount of calmag and Epsom salt youll need.. I need the requested info
but typically its about
2 to 5 mls calmag and 1/4 tsp Epsom salt per gallon

ok
so that's PLENTY of calcium already assuming your using the 8mls per gallon so theres no need for calmag
but they didn't list anything for magnesium % ???
that makes it hard to know whats in it. id like so assume it has some in it and they didn't list it??... id start with 1/4 tsp per gallon Epsom salt added each time you fertilize

for now
you shouldn't foliar feed anything unless you have a problem that needs correcting
maybe just neem oil or azamax 1x a week or 2
later when your feeling frisky you can play around with kelp, amino acids, fulvic acids, silica
but don't do it yet... itll just create more possible issues
