Having the same problem with one of my clones, pretty sure it's nitrogen,do as metic says and you should be rightWhat's your temp and Rh? What are they grown in and what is your lighting setup? Looks like too much nitrogen causing this, I would flush with plain water then water with plain water for a while untill they look hungry again, the leaves are so dark

It looks as though you have plenty of N going on....but for sure, check for light leaks and check your timers while you're at it. Good luck.
Temp is around 19-26 C and Rh is 40% growing in peat moss and perlite mix the light is 600w MH 40cm away and yes i gave too much nitrogen what to do guysWhat's your temp and Rh?

They are auto-flowers they don’t need darkness to be healthy

Looks like a burn of some sort I'd flush without nutrients or do half dosage the next two nutrient feedings

Or your tops are to close to your light Cant see in pic needs at least 12 inches depending on watts. Of lights
I’m sure that i have nitrogen burn but i also have potassium deficiency which is very confusing to deal with sense i have bad fertilizers and i can’t reach the store because of this damn virus and i did flush 2 weeks before this appeared and flushing again with water of 8 ph is a bad Idea but thanks anyway

Online order a go box bgg y general Hydroponic they have all you need plusnuts organic and the buds will be busty
I live in the middle east the online ordering is a pain itself and we don’t have respectful shops

Ah got ya. Happy growing salam alakem
I see no signs of N toxicity. Dark green leaves might lead one to think that's the problem, but in this case it's isolated into one location, and there aren't any other symptoms of N def.
What is it than?
I don't know what it is until the proper information is extracted. We want to have as much information as we can get before stating anything, or else we'd just be guessing.
Temp is around 19-26 C and Rh is 40% growing in peat moss and perlite mix the light is 600w MH 40cm away, ph of water is 8 but the soil ph is 7 my nuts are 3-1-1 in veg and i have stopped feeding since the problems show signs i water from tap water
Everything there looks appropriate, other than the fact that with Peat and Perlite, you want your pH to be closer to 6.0.
Since that doesn't look like your immediate problem, have you inspected the leaves of the affected area with a loupe or magnifying glass for pests?
When you get a single branch going funky, it could indicate pests. Looking at the pictures provided, I can't see any signs of any specific issue. Can you take closer up pics of the affected area for more detailed inspection?
