Issues since flipping

Hey guys I've had some issues since turning its probaly just nute burn, but what do you think.
5x5 tent with 3x spider farmer sf2000s
25 litre pots with 70/30 coco perlite mix
Feeding H@G cocos, multyzyme and roots excelartor at 1.3 ec and 5.8ph. 3 weeks since 12/12.
Hard to tell from pics but I have tip burn that also is on all the serrations down the leaves, slight taco leaves and the top half has a very pale looks to it. Kinda looks like the start of yellowing inbetween the veins.
Bottom of pla t looks good but maybe a bit dark green

What is the distance from your lights to the canopy? Also are you feeding to runoff and how many times daily are you feeding. In flower keep your ph at 6.0-6.3 within that range. Being pale up top on the canopy looks kinda like light stress and the taco leafs is another sign of light stress. Maybe raise your lights some and dial them down a bit and cut your feed back to 1.0ec and see how they react. Some more experienced folks will chime in soon and hopefully they can pinpoint the cause better than I but those are the things I would try first. Don’t make too many drastic changes at once just small steps and see if they straighten out.

Lights are about 14" from the taller branches and 18" - 20" from the rest.
Only feeding once per day but with lots of run-off, which comes out at 1.0 ec so don't think there's a build-up in there.
I'll try raising the lights abit, and increase the pH a little.
Might be worth backing off the nutes too as you said, I just feel in already feeding quite light especially since by background ec is 0.45.
I've never had a plant this low on the ec at this stage normally I would be up to 1.6 - 1.8 by now but I've never ran this strain before.

Maybe this can help you figure it out:

Make sure to swipe on images to see all the different angles and issues with different types of deficiency and toxicity.

Best of luck.

Yeah try raising the light a bit if you can. I would say they may be a little hungry with the light coloring but with the slight tip burn it doesn’t seem like they would be. I know I run DTW coco with flora nova bloom and I use 1/3-1/2 what they recommend and still get slight tip burn so I don’t dare to try to raise it any so I just let them roll along at 600ppm and seldom hit 800ppm but that total ppm and my starting water is 200 so it’s really only 400-600ppm of added nutrients and they seem to do fine. I’m not the most experienced with DTW so hopefully the big guns show up soon and will have some insight for ya.

14 inches isn't that much... I need to do about 18 inches or my plants start to get a bit bleached out

Potassium deficiency early.

This was another thought I had, but doesn't potassium deficiency start on the older leaves and work it's way up?

I've got it down to nute burn, light stress or potassium deficiency.

Starts on older leaves definitely.

Ok I'll ha e a closer look later at what's left of the lower leaves (as I cut most stuff off the bottom 3rd or so) but I think its mainly on yhe top half.

Also does lower ru off ec than inflow mean they want more food, or don't even worry about the run off?
I'm going in at 1.3 and it comes out at 0.9 - 1.0
