Good advise from
@TaNg !
As it is obvous that water may flow from the holes I place the pot in a tray and water very slovly, moving the water running from the pitcher is circles, starting at the base of the plant and moving outwards to the edged of the pot. Water running out of the holes goes back to the pot. The last run off I throw out.
Since I'm a beginner and a feeder - I love to feed people and plants - and have seen deficinesies, I water lightly but often, so I can add additives when I se a problem. What has surprised me is how much Mg2+ they require. They consume more than my 65 kg body. Also, to avoid nute burns, which was the first thing I managed to induce because of my love for feeding everyone and everything I care for. I made both my wife and the dogs obese. Regsrding mynself, I under ear.
I really have to restrain my self from overfeeding my plants.
