I have never had a problem with watering as I have been using the weight of the plant to decide if it needs water. I would water throughly with a little run off at the bottom to ensure the whole thing is wet. Grab the pot with both hands and lift it up a few times and get a feel for the weight. Now check it again in 2 days you will soon enough figure out the weights.

If you are not watering throughly with a little run off, odds are good you are leaving dry areas in the soil which can damage your roots.
