Irregular lookin leaves(retarded)

This is my first post and my first grow , I was wondering why the first pic has irregular leaves since day one. i cut some off but today i realized thenew ones are growing retarded also.
These 2 are my oldest they are about 20 days old from seed.Approx 7 inches tall from soil .How am i doing .. i believe they are a very potent skunk strain.(says my friend)
I also have 2 purple haze plants but they are only 12 days old..i want better quality pics of the purps...I think i will start a grow log....

Pictures are a little hard to see. Tell us what you are doing. What kind of soil? Are you Phing the water?

looks like mine

i am using perlite and peat moss about 50/50. 2- 2 ft flouros and just recently started adding 30-10-10 nutes with trace . hows that ?

Testing Ph?

oooooops !

Mongoloid leaves happen to everyone. I think the lights cause some of it. Are you keeping them really close?

not to close about 12-14 inches...but i noticed it happening since it sprouted .if that helps.and its only that one plant. i have others from the same strain and they look perfectly normal. im gunna let it keep growing though ...
