Hi this is my first grow is this the normal size for a northern lights autoflower. It's been just over 2 weeks now under 24/0 led light it don't seem to be growing any more. Please help and pictures are added MINE001.jpg
 
No that does not look like 2 weeks old. Looks like about day 3-4 after sprout.

What are the temps in that space?
What soil are you using?
What nutes?
What PH?
What lights? How far back?

Something is holding back growth, temps would be my first guess at this size, but it's a total guess at this point since you provided no info.
 
The temp is around 22, the soil is a "growth substrate-substrate mixture ph between 6.5-8.5 the nuts I'm using is a universal fertiliser 5-5-5 nkp. The light I'm using is a led panel which is roughly 2foot away. Will my baby come back to life or will I have to start again
 
My plant two weeks in...use a cfl 300w for vedge and plant a new seed as that on looks days old now weeks..IMG_20160118_220704.jpg
 
I'm going to assume you mean 22c not 22f as they would be frozen vs room temp (72f at 22c.)

The PH range on that soil is huge. If it's above 7.5 that is likely your issue. You need to test the runoff water's PH and see where you are.

The seedling still looks healthy, so it should recover and grow as normal if you fix the issue soon. There is always the possibility of it just being a runt/dud.

It's an auto the plant will not have time to catch up missing two weeks growth on the vedge stage for an auto is huge...
 
Switch to a cfl 300w seeif it helps
CFL is horrible, it's the least efficient lighting choice used to grow.

At this small size even a regular household CFL/LED bulb will work fine, you just need to get it pretty close, 3-4" back.

The light is not your problem though. Even a very low power light should not stall them at this stage. Low light also causes the plant to stretch, resulting in a very skinny stem. This plant hasn't stretched this way, so light is not the issue.

With temps crossed off the list, it leaves soil/nute/ph/soil-bugs/over-watering as your potential causes.

Why someone would use soil with the range he has is a little baffling...I use cfl in vedge and find it does great for my plants I also use t5 and mh 600w too...

Good point, forgot it was an auto. I haven't had any issues with auto's yet, so I'm curious how a situation like this would work. I know (from reading) that the "internal clock" of an auto does stop in some cases, like cloning. If you clone an auto, it's internal clock won't move forward until the roots have grown out, so they finish as itty bitty plants about 10-14 days after the mom. If the internal clock shows 2 weeks right now, he would be totally screwed, he would get one itty bitty plant.

In any case he should try to fix the issue and get the plant growing, for the sake of his next seed and to learn from his mistakes.

He might as well get some new soil, a ph meter, and start the second seed with the assumption that the first one won't get very big at least.
