I also wanted to add, in case anyone is in a similar situation, I don't think they liked my water. We have city water, and everyone was doing okay - living but not exactly thriving - but once I put my oldest/strongest outside for an hour for a drink, holy wow they said "THANK YOU!!!" and they've been very happy ever since. I have a bunch of cuttings that are ready to be up potted from their plastic cups and I will do as grasa suggested and water them indoors with rain water.
Grasa - do you let them soak in 1/2-1" water for a set amount of time? Soak for one hour then pull them out?
