Leaves not dark Green

I'm wondering what might be the problem with my plant. This photo is of White Shark, but I also have cannatonic and LA Chocolate that are similar in color. I just put extra nitrogen on them today. Also wondering if I over watered because this particular plant has some curling leaves.

I am using t5 lights and cal/mag, liquid nitrogen and biocanna vega.

probably transplant that into a dry pot.....

Look plenty green to me. But a little droopy. Let her dry out.

Ok. Thank you both. I keep getting told that they're not dark enough green.

Not all cannabis leaves are dark green and you have some clawing starting which means your pH is off.

Also, you have used to much (n) I can see it turning your leaves.. Stop using nutes for now, wait 2 weeks on ph'd water.. Soil 6.8.

looks like over nutes.... IMHO

Ok thank you. I will back off those.
