Leaves are slightly curling up and unusual color at the core...

NFT system with very light nutes, probably 1/2 what they should be. Water is pH adjusted and they are sitting under a 600w MH light. Tent is kept nice and cool, high 60's to 70's. Out of a dozen plants this is the only one doing this. It's sister the to right is the same strain and distributor, same water and light and she's fine.

Help appreciated!

I wouldn't worry too much about it until there's a problem.

Look like you have a 27gal res from Lowes. Clearly diy, but how is it NFT?
Did you mean aero or DWC?

Right. What he said.

Just because it's the same strain and distributor, doesn't mean it's the same genome. I'm assuming you bought all female seeds. They self pollenate a hermie to guarantee 90%+ female. She's just probably a little slow on root development or came from a different plant of the same lineage. The runt of the litter, if you will.
