let them dry out a little. they need very little water when small. try checking the soil near the drain holes or check in deep from the top. the roots will seek out water in the lower part of the pot, thats how they grow. if they are wet all the time there is no need to. the other draw back to over watering besides drowning is everytime you water you dissolve more nutes and eventually it can burn or lock them up or just plain turn the soil toxic.
