I soaked the pot 24 hours before planting (20% run off) then I didnt water at all for 10 days. I then gave 800ml around the plant and didnt water again for a while. Obviously you're environment will be different to mine. I think the easiest thing to do is go with the weight of the pot. If its light, water. Heavy, leave it a lone. My plants are doing well with this method :)
