Hey guys! At first sight what you can say from the photos? These are the photos from a friend I dont really know all the parameters from its grow, so what do you think?
The only thing that I can say is that they are in vegetative state.

Not adding enough nitrogen dude!! The plants eating up all the N from the leaves, are you feeding??

You're gonna have to get us some details about this, quick. They are going downhill fast.

Feed schedule
EC
Temp's
Medium
rH
Etc.
 
Well its not a lack of N, that's for sure.
More likely far too much.
Lack of proper watering practices, salt build up causing lock out or just too high EC.
JD has it right... Back to basics.

Best I can offer with nothing but a couple of pics.

I don’t agree with the fact is far too much n bro, leaves would be dark ass green and curling, that in the pic is the opposite sir, seems lack of imo, I agree with the watering practise, but the op needs to give us some more info.

Yeah but after they go dark green they start to die and yellow too. Most people don't let it go that far. So its not common to see.
But there are signs of clawing too.
I'm not saying its certainly too much N but its not too little. With a lack of N a plant will use up the lower leaves first and will always work from the lowest leaves and progress further up the plant, the lowest leaves will drop off before the mid level leaves get to the point they are at. You can see from the little info we have that the lower leaves are actually still green.

The rest is just a guessing game until more info is provided :bigjoint:

Good point but I find people get confused with that as 70% of the time it’s lack of light at the bottom of the canopy rather than not enough N and people add N and f*@k up! The general hue of the plant is a light colour which makes me lean towards N,he just may not have been feeding at all, pot size maybe too small, looks like it’s been abandoned to me in all honesty.

How can you tell his pot size from the pics? That could be like 15L ?

Picture two, bottom right corner I can see the edge of one pot ....the mylar on the left, leads me to believe that's the other edge....
That's a 1Gal square.....

In no way am I insisting that I am correct....based on my interpretation of the scale of the visual evidence, I believe its a 1Gal square.
