I did it all the time, specifically because I was trying to encourage stretch as a vertical growing technique.

If that's why the leaves are like that then thank you for answering my question.

I know you can, but most don't want the stretch.
It was just a question.
Since you have ironclad answers to your issue I'll leave yall be.

Easy there. We all have our reasons. I thought I was answering your question. If you have another point of view I'm interested in hearing it?

Here I thought he was answering me with his question................guess not. Looks like it's getting worse, anything I can do to correct this issue? Any help is greatly appreciated.

What's your temp been at?

Are you on a 18/6 schedule?

yes

If you have good ventilation and air movement then you can rule out environmental factors. I never grown in coco so hopefully someone can determine if it's watering to much or to little and nutrients.

Your new growth looks ok for now.

Wish I could help.

I think that there's a lot of bone dry coco that needs to be damp- not soaking dripping wet but damp. I'd also make sure temps stay over 25C, even 30C is good.

What are you PHing at?
Could it be a VPD issue?

Ph at 6.5
Rh at 45-50
Temp at 23-25 day and 19 at night

Not a coco grower but isnt coco ph supposed to be lower? 6.2? I know some guys water their coco from their hydro res at 5.8 ph. Maybe your ph is too high?? Ph being out can cause leaf curl etc. I agree with ttystikk, doesnt look like N toxicity to me.

Lower temps wouldnt do that to your leaves either. Just my 2c worth
