Well, it is my first grow, so the overwatering is something that I'm concerned with.

I determine when I need to water by lifting the containers AND using a $10 soil moisture meter. I'm only watering every 4 days or so and I live in an arid climate with 20% humidty. Often the top soil layer is TOTALLY dry for 2 days before I water. However, they are in larger pots than they require... straight from small plastic cups to 7-8" pots (not sure the volume, but probably a gal or more).

The plant in the pictures was watered probably 20 hours before the picture and started exhibiting the symptoms today. The plant seemed like it needed water though... container was light and moisture meter was dry!
