Hey there Pumu,
Thank you for the nice PM. I'm glad to hear I've brought a little extra knowledge to the auto scene here and yes of course, I'd be more than happy to follow this along with you and help where I can.
Firstly, your set up sounds great, they should really thrive in there. One suggestion I have while you're plants are starting out is to get those CFL's as close as you possibly dare. If you hold the back of your hand at the same level as the seedlings and it's too hot to keep your hand there, then you're too close, but really, with CFL's you can get within a couple of inches if you really want to without burning the plants.
With CFL's you will be constantly adjusting the height of the lamps as you raise them up with the plants as you'll want to keep them as close as possible for as long as you can pre-flower, so get them down low now and just expect to raise them up fairly regularly. I highly suggest you look at investing in a nice LED unit. You'll find a nice 90W-125W UFO LED on Ebay for about £50 and this will perform better than the set up you have now. Not that yours will perform badly but LED's are definitely the way forward and Cannabis loves them so do check them out some time, you won't regret it :)
Bringing the lights right down low to the plants isn't totally necessary but you may find you're babies will stretch slightly in the first few weeks and if you can avoid this then it's best to do so to prevent your plants from becoming too top heavy and collapsing .
In your smallish tent it will be a wise idea to invest some time in researching LST (Low Stress Training). This is basically bending down branches in certain places to create more flowering tops without stressing out your plants by topping them (cutting off the tips of the branches with scissors to promote a bushier growth).
Stressing Autoflowers pre-flower can really hinder your final yield so again, if you can avoid it, then avoid it. That's not to say you can't top auto's, because you can, it's just not recommended while you're still learning the ropes with growing autoflowers.
Now, on to the plants.
The White Widow looks great and right on track. That should be a great plant if it carries on like that.
The Northern Lights however looks to me like a mutation. This is fairly common with some plants, you will come across many in your journey growing Cannabis. You will just have to make to decision whether to keep going with it and either hope it reverts back to normal growth or at least finishes with a nice amount of bud.
Mutants do tend to grow some really potent and uniquely tasting weed but it's not very often worth keeping them around if you have limited space as the yield will be tiny so in my opinion Pumu, I would rip that out and either concentrate on growing a very large White Widow as the one plant can now take up the whole tent and all of the lumens, or, another option is to quickly germinate another seed to take its place and just make sure to train (LST) the WW to keep both plants growing at the same height.
I think that's about it for now but keep me posted friend and I will help as much as I can throughout your grow :)
It's a pleasure to meet you btw :)
Peace
