Whats wrong with these plants?

I got 2-3 weird plants im using peat-moss,vermiculite,perlite mix.... plants are about 2-3weeks old. I was wondering if anyone can tell me what is wrong with these few plants i have
below are the plants with problems can anyone identify

Well to me it almost looks like ph problem or you could try putting them in larger containers man those look a little small, Are you using any nutrients? because around 3-4 weeks of being in soil you may need to start hitting them with some nutes but it doesent look like a deficiency of any kind just that your ph is off causing the weird growth, get that ph fixed and you will be all set.

yeah bigger pots nute/fert feed if not already using any check your ph levels
