What are your numbers PH and PPM?
What medium are you using?
What nutrients are you using and what are your watering process tied to feeding them?
How old are they?
Looks like some are in flower while others are not.

Is it soil, coco etc
Who makes it?
Unfamiliar with it
Pic of label would help
Is it organic or chemical?
If chemical may need flushed on a regular basis to wash out the build up of salts.
You may even not be feeding enough?
From seed or since flowering?

Its soil (top crop) , I dont think that problem is in soil because i used it many times ,
from seed of course they are autoflowers 
should be ready max 4-5 week

Its unusual to me cuz Im only used to seeing calcium expressed as a percent. Damn that sounds nerdy.
Ok I get leaves kinda like that when my buds seem to spurt or spit out another layer of sticky. The ones I give heavy on calcium and magnesium dont do that.
Edited here its cal nitrate and cal citrate I got.
My stickiest stinkiest girls but its only few leaves

What sort of pH tester do you have , is it calibrated ?
I have 2 ph tester 
good ones already calibrated also I have ph tester kit and ph tester papers every of them says same
My guess is ph drift. Did you check runoff?
Light burn all over, easy to see

how? i never sprayed water to top
I agree with the light burn. I was having the same issue in one of my tents. It happened with 3 of my plants. I moved them over to the bigger tent with less light pulled the old leaves and within 3 days started seeing improvements

I’m not seeing light burn as it’s not just the top it’s all the way down where the light isn’t as intense.
there were im this tent from seed , how it can be light burn ? i dont think this is light burn , i have light burn on plant and they were burnd on top but in this case whole plants are yellow from botom to top . so this is other thing
Hey I can’t explain it. Just like you the plants were in the same tent no problem. They went into flower and started with the yellowish leaves all the way through. They are under 75% light and a higher distance and are improving. Leaves are getting darker. But only guessing, hope you figure it out. Good luck!
