Yellow edges and taco leaves

Getting some yellowing on the edges and the leaves seem to be pointing up and tacoing.

First thoughts is that it's N deficiency setting in which wouldn't be all bad at this stage.
The tops are pretty close to the light which may be the reason for clawing..

Any thoughts?

Possibilities, bearing in mind it could be s mixture are;

1. Heat
2. Light
3. RO water contains no trace elements. This is what I suspect is the cause. An imbalance as one certain element is in higher demand. Manganese has a yellowing of new growth... do you're nutes contain any trace elements?

Also, apparently leaves start to cup at the top when low in magnesium. I know you're supplementing. Which is why the symptoms are early. Takes 6 weeks for mg def to properly show..

This pic helped me out s bunch!

Oddly enough. every leaf all the way to the base looks perfect except the top leaves...

Ahhh, I stopped Ph'ing my nutes a while back because I thought I had it dialed in.. I just mixed a batch and it came out to 4.8 PH. I just added some PH up to get it to 5.6 so hopefully that straightens things out.

I'd go more for 6.0 on pH. you might be over ferting with 970. maybe cut it back if the higher pH doesn't help much.

Sometimes I get similar conditions if i'm pushing too close to the light, only affects the upper canopy. May not be the case here, just adding my two bits.

Well I have 6-8 pots per light, question is most of top of each plant have like this very small aiming to a taco shell,, but just the very top leaves
