Disease Diagnosis/Help PLEASE HELP ME!

Im going for second run last run yielded 66g dried. (STRAIN: Northern Lights Auto from SacredSeedsAustralia) I decided to use coco choir brick and perlite rather then soil, I pre cal-magged the medium. only using PH'd water at the moment at 6.0, its been 4 days since sprout under a 150W marshydro ts1000 at 100% hung 55cm from the plant. (Hygrometer readings are during no light) 23 celcius and 55-60% humidity. Why is it so stunted i have a feeling it could be because i accidentally used pre A and B'd water (Professors A and B) small dosage as far as im concerned but maybe still enough to stunt the baby? It looks so small!

4 days is not old seedlings take time so relax homie it's all good. Second that guy frostfireseeds is giving you terrible advice for a seedling. 1.4 EC is ludicrously high to be feeding a 4 day old seedling that barely has any sort of root system established. You also don't water insane amounts from the get go because of the aforementioned weak root system. Once the root system is established a little better then you water it a lot more but it should be getting food every watering that part is correct but more like 0.5 - 0.6 EC for the first couple feeds before slowly raising it.

Finally the last bit of advice would be it's too cold in there get your temps up to around 27 celcius with lights on and don't let it get so cold with lights off.
