Beginner Gardening: Growing ranunculus from tubers, 3 by Elijablue

My ranunculus were growing just fine, but several seemed to have "crashed" for no apparent reason. I have a total of 7 pots, 4 in a west-facing bedroom and 3 in an east-facing bedroom. Some from each room have gone down. All were watered the same, and room temps have been 70's, cooler at night. I have now moved the "crashed" ones to my basement under the lights, thinking that might help. Don't know what else to do. Any suggestions would be greatly appreciated. I really don't want to lose them if I can do something to help now.

I'm attaching pictures of the "crashed" victims, as well as the healthy ones.
