new growth issues

Hi, I have a friend thats growing for the first time and is having some probs.
The seeds germinated exactly two weeks ago and they are still looking too little to me (I have a growth of my own with the exact same seeds and germinated a week earlier the his and my plants are much much bigger).
All conditions seem to be fair, he used humus and organic compost (the compost has neuter ph, seeds and was treated), the room seems ok to me so does the light (400 watts HM) turned on 18 off 6, 20 degrees temperature.
If you have any idea of whats going on, if its normal or not if any of the conditions are odd or can be improved I would thank if you share with me, I m posting a couple of pictures, THX.

your "friend's" grow looks surprisingly like yours..

I don't grow in soil... so have no idea why YOURS are growing so much better than his.....

thx for the link to my other thread xD

you mean "your friend's thread"?

I think u better close your light to your plant....If not your height is taller

You should use cfl's or fluo's the first week or so.
The dirt looks really black is there any nutes in it?
Lot of a dirts that are good for growing with~but
are not good for seedling~

check your PH. there might be a lock out as your seedlings are yellow

Both Threads are mine, my grow isn't the one on this thread though, just doing my m8 a favor.

just bustin on ya a little bit - sorry man.. I still have no idea about soil grows.. too much work for me

lol that s ok......we found that the problem was a combination of too much light, humidity and lack of nuts.Now they are doing fine with some NPK nut and air extractor, but if u have advices anyway they are sure welcome, thx a lot !

actually he sent me a couple of pictures and the ladies don't look so good, I am still a bit worried, any more ideas? THX!

its probably his light is to close back that up.............and just by looking at the soil he is probably over watering those potts are way to big to start seedlings unless you know that youll only need to water bout once a week

check the ph ...

is there a way to measure ph without buying anything ? thx !
