Help determining my leaf curl

Hi so I've been growing gg4 for about two years and some seeds along the way. I have two tiger cake strains that have leaf curl that none of the other plants have or that I've ever seen. Hoping someone can help diagnose the issue. I have around 65 plants in my garden and only these two have this problem. I'm in week 2 flower. Growing with general hydroponics, Big Bud, monster bloom

Light source : 1000w gavita @ 100%
Medium : soil
Feed : general hydroponics, Ph 6.2-6.5
Humidity : 55%
Temp : 28-28

Looks like signs of too much nitrogen. I’m about 75% positive.

I second nitrogen toxicity

Cut back on the nitrogen.

It's definitely nitrogen claw.

Hi thanks everyone for reply, now that we have determined the cause of it would I cut back on general hydroponics floramicro?
Floramicro is 5-0-1.

Correct. I'd go plain water until symptoms resolve.

If your in soil, I would use just plain water for a while.
If your in soilless media I would cut Nitrogen down to around 35-50PPM (mg/L).

Thank you guys

Just to be clear if you correct it will prevent further problems but the plant won't really ever go back to how it was before clawing. In your op you said you're in soil so I'd just try straight water for a while. In flower you don't really need to boost the N.
