wrinkly sprout... please help me out...

so yeah.. this is some random schwag bagseed... my very first grow ( i only vegged then i purposely flushed them due to paranoia) i had like 16 sprouts and narrowed it down to the 4 strongest... out of those that i had taken out, quite a few had this problem... now i am sorta curious if there is a way to fix it instead of eliminating them... i only sprouted 7 ths time around and want to know if i can fully veg this one... humm.. the only details i can think i left out is when it was in the yogurt cup for the first week, i tried a lil super cropping on it... i am almost thinking that when i transplanted, i could have crushed it a lil too much in all the wrong spots... i dunno, i will put up piks of it in the yogurt cup and now in its current home... i never saw this happening before the transplant, so any advice on this issue would be helpful... i am prolly just gonna ride this one out and blame it on shitty genetics being from a grower who was just worried about yeild (commercial bud from mexico)...

none of my other sprouts are doing this at all, so i know it isnt the heat, lights, or watering... i water all the same...

i would say bad seeds, or bad genes, or some kind of shock when sprouting. How did you germinate the seeds?

soil... i sorta have this pot i put my seeds in by muh heater... i apply moisture as needed till i see some sprouts... then i take the stronger ones that break through the soil.. also, it gives me sprouts for later on... all i have to do is water a couple of times again and voila... new sprouts... i only do this with completely random bagseed collections i have... i save strain specific grows for the paper towel method... not that i have done a strain specific grow yet, but i have practiced germing that way and was succeful in getting some sprouts rooted... the only shitty part was i didnt really have the rite anything at the time to keep them going... so i cancelled that grow and focused on my micro i had going...
