Did you ph soak your cubes?

Yes i did ph them to 5.8 over 24hr. Ph in res has got up to 6/6.5 but was adjusted back down ( about a week ago) since has been steadily between 5.5 and 5.8

That's NOT high N! Not even close
What nutrients?
How much do you use?
How often?
What is the water?
Ph to what range? - How often?
Looks like K def. with Zinc def.
That denotes a pH problem (generally).
Answering my questions will allow for a clear answer and solution.
I'll comment on the soaking of the RW after that too. (you did the right thing - soaking)

looks like FE too, possibly, but it all goes back to ph issues for some reason

Advanced a+b with some thrive alive
I have my ppm at 940 (ec 1.34)
Flooding every 3 or 4 days as thats how long it takes my rockwool to dry out a bit(tried once a day and they looked over watered)
The water is 1to1 ratio distilled and non distilled well water
Ph is between 5.5 to 5.8 never above 6 checked before every watering
Thank you for taking the time to reply all help and advice is greatly appreciated as im still green at this

BIGGEST mistake is how often you flood!
You should be flooding 5 times in a lights on period!
This is considered a hydro style grow. The Rockwool needs to be damp and NOT dry out at all!
This IS causing a pH problem too! As the RockWool dries out...The pH is rising!
SO then. You have lowered uptake of K and Zinc (and other things) by high pH, too long. You also have way too low feeding availability, so they aren't getting enough to start with......
The plants are struggling to get what they need!
Cycle the system like this.
The first cycle right at lights on!
The last cycle right before lights out - (as the cycle finish's. The lights should go out) THis carries the Rockwool and the plant till lights on!
Space the other 3 cycles - evenly between the first and the last.....
Things will take off and you'll be very happy and so will your plants...
More points of order:
pH everyday at lights on! pH should run between 5.6 to 6.2.....Different nutrients are best available at differing pH values. The way I used to run hydro styles was to focus on a pH of 5.7 - 6.2....It is best to allow the swing from you setting it to it hitting at 5.7, to rise to about 6.1 -6.2 before adjusting it back down.
As the rockwool and the plant age. The pH will settle down and rise in pH slower.
The damage to the plants will not "repair". They will deepen in green from the needed N. The new growth will show nice fresh undamaged plant as it grows.....You will "see" improvement in 3-5 days.
Good luck

This look will go away once the plants establish themselves!
Trust me here. Your'e not "over-watering". That's a soil issue - NOT a "hydro" issue!

I think it's more of a cycle in 3-4 days! STFW?

What should i be doing differently? I dont plan on using RO water

I would ditch the distilled, that has always caused issues, maybe just some spring or drinking water, I bet you see them green up. Not sure about your well water, it may be fine by itself.

I wouldn't worry about the water mix! I would SERIOUSLY consider RO!
Do what I told you and your problems will go away! (you posted it in a quote - with no other response - what did that mean)

I retract my l last water statement and agree with my medical colleague on this!
