If I had to guess she is hungry for some calcium since it appears to be spread out and not really bad on the bottom. Your tap water just might not have enough Ca in it to sustain healthy growth in coco, which requires more than your average feed rate.

F..ck !! I think it has gone worse by tonight. Sprayd some epsom salt on her yesterday. I think it hasn`t worked. I don`t know the ppm to be honest. have grown 3 years without ppm with success. Only PH-meter.
WHat should I do - give it even stronger feed A+B ? I don`t have any Calcium available... I don`t want it to DIE , it`s the only one growing this season!

Get an EC meter and chalk then. You need to know the EC to know how strong you need to make the feed, and it would depend on your tap water reading and not only on your fertilizer specs. Calcium is usually locked by wrong pH rather than missing in the medium.

Id say overwatering too. Let those roots dry out or they womt work right. Then get a ppm meter and start feeding right. Id stop spraying stuff on it if you dont know what the problem is. If its over feeding your gonna make it worse.

I was feeding 2 litre every 3 days using coco mind you I was in flower with 34c+ uncontrollable heat let the coco dry out and poke you index finger into the coco if coco sticks to your finger it's still moist beneath the surface if your finger comes up clean give it a drink that's how I was told to water the plants in coco.

That's what I got with 3 watering a day:

First message.
Never got dry.
I've never grown in coco. But, when I used Pro-Mix HP by itself (also soilless), I let it dry. And, it was challenging tending to an auto started in a 3gal. It took awhile for it to be dry enough.Coco does not have to get dry, then some say let it dry...what is right in this world?!
I err on the side of dry because overwatering seems to be common. I still find myself ovrewatering with seedlings.

Maybe a hygrometer might help with judging the watering.

If you mix 20%+ compost you don't need a dry cycle. Just lift your pots before watering to see if they are lighter than usual. Runoff is also not necessary unless you'r using mineral fertilizers. (which in this case it would make much sense to just move to coco)
The microfauna is hampered by these dry- rewet cycle and the water holding capacity of your medium is degraded by hysteresis.
A tensiometer is the tool you want for this job. Like this one: https://blumatsystems.com/category/12/Digital-Irrigation-Sensors

Anyways.... after a post here with "maybe it needs more nutrients and feed with every watering" I upped the dose of A+B a little, so I gave 1.5ml to 1L of PH´d water. Also sprayed some epsom salt. Today I see new growth almost white?! Also older leaves getting brown on edges Pls see pic below.
WTF do I have to do then. Wash with pure ph water only?! Sad to see her die slowly....
