10/25 - roots were coming out of the bottom of one of the solo cups, potted that one up to a 2 gallon pot
10/26 - checked for roots in the second cutting and didn't find any, sent her to the compost bin
10/27 - fed and watered, gave her a half gallon of water with nutrients
10/31 - fed and watered, gave her a half gallon of water with nutrients
You need to be watering the entire container every time until you get 20% run off at least.
Then allow the top few inches to dry before you feed or water again
Good luck
