Newbie with questions

This is my first post and my first grow. This site has given me lots of great info. Now I have some questions. So here goes.

I started with bagseeds from good mid's I've had. I germed 21 and got 18, I planted 18 and got 15 sprouts. Of the 15, 13 still look good. They lived the first 2-1/2 weeks under 4-40 watt fluors. They've been under a 400 watt MH for the last 2 weeks and seem to love it. When I switched lights I replanted to 3 gallon pots. They are ranging from 6-12 in tall and 5-8 nodes.

My first questions are,

How do they look for 4 weeks?
When should I start 12/12?
What might be wrong with the sick looking 2?
Are they worth keeping?
Any other comments welcome.

The first picture is my light. 400 watt MH shop light.
The second is the crop at 4 weeks. A lot of plants for the area, just hope to get enough girls in the end.
The third is of the 2 sick plants. Started changing from the bottom up. The leaves on the right one are curling around the edges but the color is looking better maybe, (I'm color blind so please don't think I'm stupid if I get it wrong sometimes).
The forth is of the best 2. The left one is about 9" tall and twice as wide and working on it's 8th node. And the one on the right is about 12".

They dont look too bad for 4 weeks, im guessing they indicas, nice tight node formation. The yellowed ones appear to be using nutes from the bottom leaves to continue growing, so they need some feeding or ph adjust, as it could be nute lockout. Did you use all the same soil mix for every one? And if anything, what have you fed these? What are you watering em with? Bed time for me soon but ill check this in the AM.

How do they look for 4 weeks? Great! Keep up the good work! I suggest a little superthrive, a drop a gallon. Helps with stress.
When should I start 12/12? Depends.. They get HUGE when they go into veg. 2-3 more weeks and you could goto 12/12 and have some really nice sized plants. If you don't have the space.. NOW!!!
What might be wrong with the sick looking 2? They are being bitches. If you have luck similar to mine, they will be female dwarfs. I have one right now that looks so goos but its 6 inches tall, lol. I kept it because i want a picture of it when its done. It'll be like 2 solid nugs on a 8 inch plant, lol.
Are they worth keeping? HELLS YEA! Nice work!

I appreciate the replies.
I used MG and Scotts potting soil mixed with perlite. Not alot available in my area in winter on my budget. Both soils had time release nutes. I was going start feeding them once they started flowering.
As far as room goes I can't go much more than 5' with out getting to close to the light. I've heard they could double or triple thier size during flower. Good Night.

then 12/12 tommorrow, lol

Might be a little nute burn on those 2 then. they should pull thru and be perfect dwarfs, heheheh

it looks like you have plants sharing pots...... thats not going to work out very well.

I know. Its only 3 of the pots. I couldn't bring myself to throw them out. Like I had said I got more than I was prepared for. I wasn't expecting to have this many plants at this point, and still worry about how many are going to be girls.

I don't think they are ready to flower. So could I change to 12/12 untill they show sex, then go back to veg for a few more weeks? What if any would be the side effects of this? NEVER MIND THIS ONE FOUND ANSWER ON ANOTHER THREAD.
Should I just leave them go if they are all girls and just expect smaller plants?

I have no idea what your talking about... I wouldn't intentially flower to revert back to veg, that is redundant.... and yes would have harmful effects on harvest weight and quality....
