Hey Char, check out your roots, because when the soil gets cold the roots do too and it will stop your growth right now. It happen to me so i put a something under the pots and the growth started back in a few days. I also have put them in a box to try and keep the soil warm. Hell i wrapped my seeds in my electric blanket till they popped and now in a box with a light on 24/0 to keep the soil warm enough till i get my lights up.

Nice looking plant man:thumbsup:

Just a thought bro, good luck:rasta:
