Welcome To the community, I would go ahead and transplant into a fabric pot With cannabis friendly soil backfill the stem up To about one inch from the foliage. Also you might add a small fan create a little breeze.
Happy growing !
Welcome!! I agree with @kellydans i would transplant them now and bury them to help support the stem.
It helps to post some info about your grow setup aswell! Lights, soil, grow room, etc. There are alot of amazing folks on here willing to help and wanting to see you succeed with your grow!! 
Welcome to the forum @JonPom 
@kellydans has some great advice worth following 
So does @Strungthru 
While i am a grower in training, i may be able to help in some way! And if not, i have met a few people on here that should know, and if they dont, they know someone who may!
Its a big network of grow brains! 
Welcome to the forum! The growmies here definitely won’t steer you wrong! Enjoy the process. 
Tbh… that’s all I have (it has a lid and light but not in pic) why is one tall and one low? I am wanting to plant outside so can I put them in a large pot? Does anyone have a link to a Bunnings potting mix which is ideal?
Thank you all for your help

Yes , You can put plant in a pot and grow outside done it many times. Each plant has its own personality , Some plants grow faster than others. The one seedlings is Stretching for more light .
Welcome! Do you know what type they are? If you go outdoors, keep the weather and length of day in mind.
Welcome to the community 
Lots of great and knowledgeable growers here. All willing to help everyone succeed with their grow! 
What soil do you recommend from Bunnings please?
I like the fox farm product ocean forest or happy frog would be a good choice.
@JonPom welcome to the family my friend happy growing
G’day @JonPom can not help with the soil but there some of your country mates here to tag and maybe help you. @Blackmoon being one off the top of my head.
Bunnings doesn’t have good potting mixes, neither does anyone here nowadays. It’s all crap unless you modify it. If you don’t want to modify it, make sure you buy a premium grade potting mix, but even that will probably be an issue. To modify the potting mix you simply add coconut coir to any potting mix in a 50/50 ratio and it will make a much better mix for the plants.
The coconut coir is available from Bunnings and should be rehydrated before use. You buy a block and add it to a large plastic storage container of water. Then measure out equal parts coconut coir and potting mix and mix them up and use that for the plants. Use a plastic pot for measuring out the amounts.
Most premium grade potting mixes have fertilizer and wetting agents in them and these are pointless when it comes to cannabis, at least the slow release fertilizer is (there’s not enough and wrong combination) and the wetting agents aren’t that helpful.
You will need to add a fertilizer of some sort. You can use Thrive all purpose soluble fertilizer for the vege stage. And Thrive do a flower & fruit soluble fertilizer that is good for the flower stage. Thrive is made by Yates and can be bought from Bunnings. Use a half dose for baby plants and a full dose for plants more than 1 month old, in a 9 liter watering can and water them with it each week.
If you don’t want to use mineral fertilizers and prefer organic, you can add mushroom compost, worm castings and mix them with the potting mix (in addition to the coconut coir). Then you can add composted sheep or chicken manure (make sure it’s well composted before use). You can also buy chicken manure in dry pellets and add them. But the mineral fertilizers give you faster and better results.
You should also add some calcium and magnesium to the fertilizer each time you fertilize them. Bunnings sells calcium chloride and you can buy Epsom salts from any supermarket (get one that doesn’t have perfume added). The Epsom salts need to be dissolved in hot tap water. The calcium chloride dissolves in hot or cold tap water. I just add 1/3 level teaspoon of both to 1 liter of hot tap water and stir it up. Then add the Thrive fertilizers (1 heaped teaspoon of each). Stir it up a bit and pour it in a 9 liter watering can. Fill it with tap water. Check the pH (you want it around 6.0-7.0. Then water the plants.
Well @randylilgnome
Thats a pretty good response
To @JonPom post 
Thanks @Bentstick for tagging me in.
Cant think anything more to add really
Not sure where jonpom and randylilgnome are based
Yes we have a bunnings in nz
I buy my soils from an organic living soil company
Cheers 
Hello @Blackmoon how is the garden doing.
In my experience nearly all those Bunnings bagged soils are total rubbish, and dry out really easily. A friend put some on his lawn to top dress and that was a disaster as it was full of wood chips and all sorts of stuff…
yep. got some soil in bulk from Bunnings and was filled with bits of plastic and trash. Tried my best to filter them out but I’m still pulling out bits and bobs of plastic from my garden years later…
It’s mostly pine bark and “green waste” bin contents so full of plastic chunks because folk don’t follow the green waste bin rules.
If you’re stuck buying soil from Bunnings, buy Coco Peat and some manure and mix, while it’s not proper soil it’s way better than buying backs of fake dirt.
thats reviews of Bunnings i found aussie and NZ reviews as ive never heard of that brand. I use MotherEarth brand.
and ive found hundreds more BAD reviews of that soil. best advice try to find another soil
Hi there @kellydans
Its been a crazy start to my season
I took on the biggest seed drop ever and it went pear shape for many reasons
Some i still dont know why for sure.
Some reasons
Wrong soil mix, mix too hot, temperature too cold then too hot due to fire place going, not regulating the temperature of the heat pad, over watered, not around enough at crucial times due to work
Lost a lot of seeds
Repeated lost more.
I did learn a few things in the process and did save many seedlings that would have otherwise died.
It was such a cold spring this year.
Anyway things have stablized and the survivors are chugging along.
Ive even got a tiny fem pandora seedling a month old starting to flower
Thats how mixed up its been.
Some seeds just didnt want to start no matter how i started them off.
I still dont have any in there final bags yet.
Thats the next job
I gave my mate some of my seeds including my aficionado voodoo Larry and they all turned out male
He grows under lights
So i have taken them males on
5 different strains
Keeping them isolated and separate is a trick in itself.
At least i dont have any female around in flowering if any pollen gets loose.
Well i do have 5 autos well into flower
Time will tell i guess.
Ive got a good amount of pollen from a strain i created green crack x hollands hope
So thats in the freezer waiting for the right time.
For some one thats not really set up for these projects i take them on anyway.
One way to learn i guess even if its to know not to do that again lol 
So how it it all there in the smokey mountains
Getting some restore after the storm damage
Still hard to imagine that area in so far from the coast getting hammered so hard.
But i do know it can rain really hard there even without a hurricane 
Thanks for checking in
Take care
Cheers
Your my portal to a time i lived in America
And the smokey mountains
They will all be bare and covered in snow now
