ok, here is what i like you to do.
Bring heat up to 82f and try to get the humidity to 65/70%. hang some wet cloths or towels around. it helps, but you might need to keep making them wet. humidifier would be very beneficial
Put a fan at the bottom so it blows around the fiber pots, have another one blowing at the light
don't water, touch, feed or anything for the next 5 to seven days and then update with picture, temp, humidity
Also, since you recently water/feed them and you have some water in the catch cans. Measure what the ph and ec/ppm is
