Leaves that not receive enough light shows nitrogen toxicity?

[xxorezxx]

Hello guys ! I got some super healthy plants, I'm actually growing in coco with EC 1.0 and PH 5.8, my starting EC is 0.04 and I raise it up to 0.2 with cal-mag, then add the nutrients and boosters. I water once a day.
The problem is that Some leaves which are not receiving enough light due to the position of the lights start showing some symptoms like nitrogen toxicity, I wan't to know why this happens and how should I react to that problem in order to get the best yield possible. (Actually I'm trying to rotate the pot in order to the plant to receive light from all sides)

They are 1 month old at the moment of the photos.

Plants need light and co2 for photosynthesis

Less light = less ability to eat.

You need more lights... a light mover,... or a good trim/training job.

The curling looks more like wind burn to me than N tox.

Leaves that dont get enough light usually seem to have N deficiency not N tox, because without enough light they wont produce cholorphyll.Evenually they will be sacrificed. This isnt what is happening here.

In my experience, the leaves located on the lower half of the plant may yellow out eventually from light deprivation, but the the top half looks just like pics above. Not enough light, potentially roots remaining wet tool long causeing the downward curl.

That's a damn good point.

Wind whipped. Those leaves are a sign.

I want to add that there is no fan on the room, just the air intractor and extractor. I don't think that it could be wind burn, because there is no wind hitting those leaves. Also the girls affected are totally separated one from another, the only common factor of those affected leaves are not enough light. I want to believe what coreywebster said is the more adequate answer.
Now I should add more light or eventually remove those branches which don't receive enough light before triggering flOwering?

I'll try both I think.
