shes about 2 and a half feet tall in a 3 gallon pot with drainage holes and she is a little droopy with tiny holes on the leaves. some of the leaves are yellow and some have died. what i cant fathom is wether or not im watering them too much or too little. getting about 15 hrs of daylight. i put about 250 to 350 mls of water in today and misted the leaves a little. how much should i be putting in for a plants of this size?
