Too much light?

Personally, I wouldn’t jump to conclusions about light too quickly. Cannabis loves light very much, and yes there are diminishing returns from increased light levels.
However, from my experience It’s important to take a holistic approach.
There’s a very symbiotic relationship between plant environment above and below the root bed.
with increased light levels, the cannabis plant will be hungry for more frequent feeding and possibly even more nutrients than you might think, in order to conduct photosynthesis at the rate at which you are asking it to perform.
You might not necessarily be giving too much light. You just might not be treating the plant with the right support to chew through all of that light you’re throwing at it.
does that make sense?
All too often, a caring grower will see leaves like that and think “oh no, I’m giving it too much of this one thing” or “there’s a deficiency of ________” because of someone’s reply on a forum somewhere.
you sound like you have the Capacity to closely monitor what’s going on in your grow space. Sticking to an exact pH and EC as prescribed by people on the internet or your nutrient manufacturer is never, never enough to go by. You must consider everything at once and try to understand why the plant might be displaying signs of stress. It might really love your light. But it’ll get more thirsty.

Light would affect tops 1st.
I would put my money on ph issue. I would bet yoir not watering enough and you have a salt build up. Measure the run off ph and ec. Bet both are too high.
Calibrate your pen too....that can easily drift

Not my grow but there’s every factor in check from my perspective. Ppfd, ph, ec, humidity, temps, vpd, complete plant food should be in correct range. Only factor im considering is that there’s migro report from telos which says that they might create hotspot where ppfd in significantly increased. That’s why I’m thinking about too much light since I’ve seen that kind of damage from too intense light.

Alright. So what you suggest? Flush, ph pen recalibration and continuing with normal feeding regimen?

Like others have said, check your runoff ph and ppms-it's not super reliable but it will tell you if something is way off. To "flush" in coco means simply to pour more of your ideal nutrient solution through the media, not to flush with plain water. Flush it with the PH and PPMs you want for your plants. Coco needs to be fed regularly to keep salts from building up and to prevent PH swings. You might want to consider feeding multiple times per day with a lower EC like 1.0, with plenty of runoff, and I bet your issues improve.

If it’s ph lock out I’d flush with GH florakleen to clear chemical bonds that cause lock out. I’ve been ”flushing” with 1/3 strength nutrient solution with correct nutrient element ratio to lower run off ec when needed with success. I’ll go to my friend tomorrow and we’ll measure run off ec/ppm and ph. After that we’ll correct that. Thanks for all of you.
