When I water my potted peppers, they all get pretty much the same amount of water, as I have a small jug that I've discovered provides just enough water to soak through the soil and just start seeping out the bottom of the pot.
Well, at least this is the case for 3 of my 4 plants. One of them seems to hold less water than its peers, because when I give it the same quantity of water, it ends up with much more water in the dish under the pot. I get the same result even if I wait longer between watering sessions, and there's no "flooding" on top of the soil, so I don't think it is a case of that pot being over-saturated.
Also, the plant itself seems healthy and has started flowering in the last few days (it's the third of the four to start) and is of comparable size (in height and leafiness) to its peers, so it seems to be keeping up, it just seems rather strange that it takes less water.
