What type of nutrients do you give them and is it always the same regimen or do you hold some things out for certain reasons? What type of soil is that? How many weeks in flower are you at this point? Have you only been seeing your flowering plants by HPS light and you do not look at them under normal lighting on a regular basis? (Makes it hard to learn to read a plant my friend). Ok what about temps, humidity, do you spray them with anything? How long do they take to dry out? What else are you doing? Load me up with info so I don't make a bland call of uptake problems.
 
You have a potassium deficiency. Most likely caused by the ro water.
Heat stress can mimick potassium deficiency as well since it causes the rate of transpiration to surpass with what the plant can keep up with. Thus causing cell death starting at the leaf margins.

I'm using advanced nutrients and what ever week they are on I give them that weeks nuts like some say weeks 1 to 2 use this 2 to4 use this rn I'm giving my girls micro grow bloom, budcandy, bud factor x, big bud, b52 nirvana. And terpinator

Sunshine mix 4
Temp 80-82
Rh 45-52
I spray green cleaner once a week for maintains
And b supplement that is suppose to help leaves just started that since my leaves look like shit

I run a perpetual so I have strains from week 2 to week 6 usually I water every Monday we'd and fri they are usually pretty dry.
 
My last 4 plants grew in soil looked similar to yours kronic kush as i was into about my 5th week of bloom the leaves crisped up and got to a point were there were no leaves left, only buds. I think it might have been due too heat stress tho as i had 4 in a cupboard with 1 600 hps bulb.
also lack of nutrients because all i used was bio bizz,topmax, grow and bloom along with ionic pk boost used for hydro.
Advanced nutrients ancient earth, sensizyme,overdrive, big bud and part a+b is what im going to use for my next grow.

i'm hoping my new solis tek air cooled light and matrix digital ballast will have much better effects on my plants and make them grow good quality roburst buds. I might have overspent a bit on my new equipment as I am not a pro.
IF anyone wishes to instruct me on a proper nutrient feed schedule please do!!
