This is my first time growing and I have a quick question about water. I have a pretty simple water meter that tells me if the soil is Dry (1-3), Moist (4-6) or Wet (7-9). My plants are still small, only a week old. At about halfway down the pot, the meter reads 2-3, being pretty dry. However, at the bottom of the pot the meter reads 5-6, fairly moist. Should I water when the pots are dry midway down because the plants are still small, or wait until the entire pot dries out? Thanks
