please help me with these plant problems

Jack 47 planted from seed 3weeks ago, plant started growin fine, last 2 days leaves started drooping and curling now i notice small brown spots. Im using cfl's for now and the fertilizer is a miracle gro moisture control potting mix. I have a black jack plant same age, height and soil but im not having any problems with this one. Please help me fix this problem before its too late. Thanks alot in advance.

does the soil have time release nutes

yes the bag say "feeds plants for upto 6 months" After doing more research im pretty sure its over nutrients thing, im gonna get more opinions. Im transplanting today into 5 gallon buckets so i will probably end up buying a soiless mix or a mix with less nutrients. My other question would be why is the BlackJack not doing the same thing? The roots are also strechting out the bottom of the 1 gallon containers on both plants is this ok, with the plant only being 3 weeks old from seed?

if your roots are growing man, let em grow as much as they want , shit...

If it's not too wet or cold i would say ph-value off or some bad phenos.

how long do you think before I should transplant into a bigger container? I was gonna do it today but im gonna wait a couple of days for the soil to get drier since i will have to soak them again to transplant. These are gonna be my mother plants so a 3 or 5 gallon container should be good for them to stay in.

I think you found the problem then. The plants can take some cold, but water needs to be warm then. Is your water warm?

im using tap water that i let sit in the growbox for at least 24hrs to get the same temp, but the last couple of days it has been colder in the morning between 60-65f, im gonna let them dry for a couple of days and see what happens. So far the problem hasn't gotten any worse, and im keeping a closer eye on the temp and humidity. Thanks for all the advice it is greatly appreciated. Should i clip these leaves off? or just keep them growing? besides the obvious "problem" how are they looking?
