I reckon that's it, auto's I have grown have been small. Also when I grow normal weed. I veg them 2 or 3 weeks longer than the average auto veg period.
White on the node could be a pistil, if it looks like a hair. That means it's a girl and it's starting to flower. Male plants have little balls. Like I said without a pic, can't really tell for sure. Could be a fungal infection.
Just check out the how to grow section of the forum. There's...
You also don't have to worry about light creeping in during dark periods affecting yield.
Also very time I've grown auto's. I find I don't need to feed so much as a regular plant during veg.
I use Kitbagshop and hhh supplies mostly on Ebay. Good prices. I also only grow 2 plants at a time just in case I get busted. I also make sure no light or smell leave the room.
Nice, this is one of the strains I want to grow this year. I love Green House seeds, they got good germination rates. My last grow was their Cheese and it was easy to grow, yielded great and a nice smoke.
Depends if you're using one big CFL or loads of little ones. If you got quite a few of them then you can use mainly blue (6500k) with a couple of red (2700) bulbs, then switch to mainly red with a couple blue for flowering.
If you got just one big CFL of each colour it will be fine just to swap...
