I didn't know how much fertilizer you were using, but 2 tsp a week shouldn't be enough to cause much trouble, as mdvpc said.

You may now be narrowing the focus down to heat. The green pots vs lighter colored ones seem to be showing a difference. Five gallons of "soil" is probably enough for roots and nutrients, but the one factor people usually neglect is the insulating value of larger containers.

I hope your plants make a nice recovery, and I believe they will once you "pot up" to a bigger size container.
