At a guess, without a description to your problem. Way over nuted.

What's the ec of your feed? Ph?
What's the ec of your waste/runoff? Ph?

Looks like low humidity too. Though you state it's fine.

How close are your lights?

Is any of it old damage? Damage from before?

I don’t have ec on I have ppm at 700 scale last full nute feed was last week at around 1600-1700
Then I did flush with advance nutrient revive
Then one more time checked run off ppm it was around 1500 ppm
So I gave nutes at 1/4th strength yesterday
Tomorrow Is the next feeding

That’s the first thing that came to my mind to much nutes

Likes around about 2 feet away from canopy
This started 2 weeks ago some of the fan leaves dried up

Yeah 1700 ppm is huge for coir.

2 feet, is pretty damn close for a 1000watter. 3 feet is ideal.

I have dimmable ballast
I usually grow with 75% instead off 100% this is my first run doing it
That’s why I had heat stress and light intestity

OK.
2 feet is perfect for my 600. 1 foot is too close. 3 feet is too far.

You're at maximum hight, for your hood? Obviously can't raise it?

Also I never go above around 1000ppm, for coir myself.
You'd have to, have some monster plants, to be feeding 1700ppm. 6foot plants +++

I'd definitely start by lowering your ppm.

Yes max height
I will switch to 75% tomorrow morning
And order some 600w lights
Any recommendations ?

Also you think if I switch over to kiss/Lucas/h3ad method during this stage of growth will it affect the plants?
