Culling the crop

Should I remove the Weak Slow growing seedlings i've sprouted? It has been about 3 weeks now and 2 of my 10 plants look awful the other 8 look fantastic.

First grow and just unsure what to do. mostly wondering because I have 2 plants in one pot, and if I removed the sickly one I'd have a free pot and could separate the two thriving ones.

you shouldn't have 2 plants in the same pot anyways but yes remove the sickly one.

no point wasting space on poorly producing plants that you will eventually have to spend time caring for and diagnosing problem after problem and eventually harvesting and trimming for half the harvest of the healthier plants.
kill the lazy plants and replace it if you have room with something worth your time

thanks for the replies, I was pretty sure that i should have removed them but its just so hard to kill em off =/ ee gad what am i going to do when they start showing sex heh.
