Hello again mate. After reading this, I've spotted something else you need to consider. You also have a problem with your Ph!
Don't set it to 6.0, set it to 5.5-5.6 and then you should let it drift up to 6.2-6.3 and then take it back to 5.5-5.6 etc.... This allows maximum uptake of all nutrients. If they have not been below 6.0 throughout the grow they will not have taken up calcium and magnesium in sufficient quantities.
As for the ec, set it 0.2 above your background to start, then watch the plants and only raise it, again by 0.2 if the leaves start to go pale. If they go darker, back off the feed by 0.1. But the ph is the most important factor, along with the growing environment of course.

Yeah pw is right mate, that was why I asked about the pH. Should go up in veg then down in bloom. If it's not then your ppm is too high so must be rising.
You want the ppm to always be dropping just a little. That keeps the pH in range for the longest possible time.
If you can keep the ppm right you shouldn't ever need to adjust the pH out with top ups or Res change day.
Sweet spot for that size will be about 300ppm or 0.6ec plus your water.

Sorry for the late reply I ended up giving up on them just waiting to get some new clones and I'll try again

I've got some clones coming in the next 2 weeks, when I do get them what's the best way of starting them off in the nft and getting them to grow away happily, please answer any questions below...
In the photo that's how much I rooted them before putting them into the system, is this ok or do they need more roots?
Once I put them into the system do I run the pump 24/7 straight away?
I'm using the standard 1000 pump that comes with the 604 systems, is this pump big enough?
The trays have a factory set slope is this OK or do I need to slope the trays more?
Thanks for any help and advice I appreciate it!

If possible at the points on the trays where you place the cubes. Build some clay pebble mounds. Then run the system and add or remove from the mounds so you can see moisture but you can tell the cubes aren't going too get soaked.
Keep the water running to wash any residue off the pebbles.
Clean and set ya res up . Personally I'd just feed them rhizo until the roots are established at 0.2 above base and ph of 5.8 .
Have a timer running the pump 15mins on 15mins off .
Once you have seen the ec dropping and you know the roots are established start feeding them.
You need the roots to go looking for that water and if the cubes get too wet they don't kneed too . Although they have to remain moist.
You'll find two of the above members are now banned
