Leaves. Curl up

Hi friend! Curling up can happen due to heat stress, high humidity levels or root problems, like over watering them. Nitrogen deficiency makes the plant look pale, lime green. Try to find some lower leaves that look too yellow and try to pull them off, if it's hard to pull off, no nitrogen deficiency, because leaves use to fall for their own when it happens. They should not look pale or lime green, when it happens plants use to have some problem and they grow slow. Like you have said, numer 1 is growing slow than others, so yes, maybe you got some nitrogen deficiency bro. It maybe could be some iron problems, but I dont think so.. but check for yellow new leaves too. Iron just affect the new growth. Like you said you have raised the light, try to raise the nutrients too, maybe they just have used up all the soil nutrition and need some more now. Happy grow!

In my opinion you have some massive pants for such a small tent and the air doesn't flow as it should this cause a high humidity on your tent. And when you are in flower stage you need as less as possible of humidity.
Looks healthy all you plants.
My advise to you is a defolage technique so you will have more free space for the air flow.
And try not over water your plant so it can get some oxygen to make a root cycle.
Hope is helpful to you.
Happy growings :ok_hand::ok_hand:

I agree with your comments it’s a bit mag sulfer deficient. Raising the light will help because in your pictures you can see the lower leaves are not as badly affected. Be careful adding more nutes as they will usually have more micros than you need causing other problems. Your better off raising the light and waiting a few days to see if there is any improvement rather than making too many changes all at the same time. That makes it easier to keep track of what works.

Without EC/PPM levels it's difficult to recommend to up or lower it.
Color wise they look fine if perhaps a bit light green.
There might be a bit of over watering more than any deficiency.
