yea yeast water and sugarYeast water?
yea but i dont wanna have to change the water if it wont do harm(its alot of work)can you not change the water seems like an easy fix as far as the stuff on the leaves i wouldnt worry i have hand washed plants individual leaves for bugs/eggs used a damp cloth and lightly wipe the leaves(im not really a pro so dont be hasty)
Sunday............It shouldn't be much of a problem. When do you plan the next change?
