They don't look so bad. You don't need that jar unless you live in a desert. Maybe a bit too much nutrients from progression seen day 6 and on in pictures.
Ease up on the ferts. They don't need any the first 7-10 days, as what it needs for that period of time is all contained in the seed.
The slow release pellet is a bit concerning in the one pic. Those are difficult to use with precision. You need to baby the plant the first couple weeks when it comes to watering or fertilizing, the latter should be few and far between and not at all initially, unless hydroponoic grow -- looks like soil, though.
Any extra stretch, move lights closer... If nodes stack on top of each other with zero internodal space, move light further away.
Try not to be proactive with them... react to what they tell you and be certain before you add anything to soil. Always better to take a hands-off approach for a day or 2 to be certain of a problem before acting.
The leaves look liek they are darkening and starting to misshape a bit... that's why i say you may have feed too much... lots of reasons i could be wrong too. So, dial back and observe. Be more certain.. i bet it improves during that time and the answer will be obvious without further investigation or effort.
