ya i would probly go with over watered it wouldnt be a fault of my own because i wait at least 5 days b4 i even think of watering but i have noticed the water doesnt seem to drain quite well in red lastic cups and the bottom soil never seems quite dry enough.
im thinkin i should maybe add some more drain holes to the bottom of the cup. or maybe i should transplant but i fear since they are fairly small and already stressing that it could severely stunt them more or even kill em
