should i eliminate my unhealthy plants when i switch to 12/12?

I'm growing several plants, one pot ended up with two seeds, which was an accident, I decided to keep them together since they were doing fine and I didn't want to mess anything up. it's my first grow so I'm experimenting. I've decided to change over to 12/12, from 24/0. Since two of my plants aren't doing great, I was wondering whether I should eliminate them now since they're not really thriving, or should I give them a chance? All of my seeds were put into soil the same day, but the 2 that aren't doing so good, were transplanted to bigger pots just recently, i think they might have gotten root bound since the roots were poking out the side of the fiber pots i had them in. Also, the first set of true leaves died on one and are starting to die on the other, and the little tiny leaves that help provide nutrients in the beginning are also dying off, however they're still intact on my other ones.

The ones in the circular pots are the ones I'm wondering about, the ones in the square pots are the ones that are doing fine, all the same exact age.


i have one more to upload thats unhealthy, since above is only one... its not lettin me upload them so give me a minute to get that one up too

heres the other one.

First of all, wtf type of pots are those. Second, the plants are absolutely fine. I would only pull if space was an issue but with 5 plants that are under a foot tall, space can't be an issue unless its a pc grow. The small leaves(cotyledons) always die off, this is when you or the soil starts feeding them. The first real leaves usually die off eventually but I like to lollipop so they get removed anyway eventually. The ones in the bowls just got stunted a little(learning curve). If some of the plants were root bound, give them time to get adjusted to their new home before flipping to 12/12

they're just regular pots... square and circle ones lol, the circular ones do look like bowls in the pic but they're just cheap plastic circle ones. so you're saying they may have just gotten stunted from being in a small pot for so long? I have read about the cotyledon's falling off eventually, I just wasn't sure since they only fell off my smallest plants so far, the ones i would think needed them the most

If you don't have enough space to comfortably flower all the females then you should cull the weak ones. If you do have the space, give the more promising plants the primo spots under the light.

I wouldn't flip those until you get them bigger

Thats what i was talking about lol. They can get stunted from a lot of things and being rootbound is one of those things. What size space are you flowering in and what light are you using to flower?

thats what i was thinking, i moved the healthier ones to the front so they can get most of the attention , i actually have 4 healthy ones I just didnt get a picture posted of one of them.

im in a little closet, and I'm going to use CFLs to flower as well. I'm afraid of using anything to jump my electric too high since i don't see that bill, my landlord deals with the utilities. thats why i was wondering if it would be worth it to continue to let the little ones try and catch up, or to cut them to use the light on the healthier ones.

I would recommend looking into T5HO lights since they are low on electricity, less heat and more lumens than cfls(watt for watt). You can also use the cfls as side lighting, since neither get great light penetration. If they are feminized seeds then I would cull the weak ones, if they are regular let em be
