Please help before it gets worse!

All of my leafs look great in color but I have one leaf starting to do an undercurl.

I use a A/G7 classic and just the standard a/g nutes for the moment.

PH is ah 5.8

Grow area 81.3 degrees

Reservoir is 74.7

With a 30% high for humidity and a 18% low.

Still waiting on my ppm meter

She is 14 days old

Any help would be great.

Here we go a better pic. (this is also my first grow so I apologize in advance if I am just being a worry wort)

my opinion is that your too worried too early. it looks nice and healthy to me, sometimes old seeds or week seeds can display genetic abnormalities when they are under early stress, same as if you attempt to flip a plant back into Veg (they get all wierd for a long while before they straighten out). as it gets a bit older, transplant it into a dixie cup (not clear, as roots dont like light) use a lightly mixed base nutrient for the first while, alternating with water. then as it strengthens you can begin mixing in your other nutrients.
