Curious curled leaf

[shizznizzle]

Hello all I am a new grower I am in seedling stage day 6 out of the ground I have this one little seedling that looks healthy as can be but she has this weird curl to her leaf. My setup is
4 x 8ft T5 18/6
3:1 FF light warrior and OF
Pure water pH 7.0 every other day
Temps are 90/78 @ 46 - 58% RH
206 ppm

Any help is greatly appreciated. Thanks!

Thats quite funny really, I'm having exactly the same issue with one of my babies, (Bubblegum Strain) - Only the plant out of 6 has Slightly downwards curling leaves, Same conditions between the lot, I thought it could have been over/under watering but I trawled through the forum and found it can be quite normal for some plants, Also alot of the people i talk to grow various things - They all said it's probably nothing to worry about - But just keep an eye out on it.

If you do come across the cause of it though - I'd like to know all the same, Maybe it could be bad? :S Who knows.
