great pics of my first grow, im on 5th week flowering, sog, need ur opinion..

that's my firs grow, read lots before started. i want ur opinion on few things. i have a bit of hight problem, so i put the net for it, and started flowering between 8-10 inch.(4 females) i am happy with the development of the buds. in using 400w hps, 1 foot from the canopy. i use 1.5g pots. do u think i should use bigger ones next grow? would 2 plants at same space (5.5 SF) will give the same crop? i thing i should set the net lower next time, this time i set it 1.75 feet from the start of the plant, and some flowers are under it. do u agree?
one of the four has much more brown-orange pistils than the others, and the colour of it leaves is darker. the seeds i used was all from friends buds of special skunk and from the same flower, so how can u explane the differences? should i do something about it?
pls let me know what u think about my plants, happy to read ur comments
the pics are dated, last ones from 10-31-2010

looks good for what u got into to it screen is to keep plants from braeking under weight if this did not happen your good on the hiegth.

Looks good sized for the pot its in, what size are they a gallon?

1.5 gallon (6L) pot

i made them grow about one foot under the net along it before i let them grow up into it. from this one foot i have got lots of buds and branches coming up into the screen. but i think that if the net was 0.5 foot shorter, i would have more buds up the net, getting more light.
