Problems after transplanting to a fabric pot

During the 10 days they were in the Solo cups they seemed fine. 1 week into the fabric pots and they don't look healthy at all. Lower leaves are almost all turning yellow. Still keep them under a T5, 6 inches away, outside during sunny days (today)

Any ideas on what's wrong with my plants would be greatly appreciated

Looks like over watering to me...

Could be, let her dry out a bit
